igc_add_mac_filter() doesn't allow us to have more than one entry with

Current igc_rar_set_index() implementation is a bit convoluted so this
patch does some code refactoring to improve it.
The helper igc_rar_set_index() is about writing MAC filter settings into
hardware registers. Logic such as address validation belongs to
functions upper in the call chain such as igc_set_mac() and
igc_add_mac_filter(). So this patch moves the is_valid_ether_addr() call
to igc_add_mac_filter(). No need to touch igc_set_mac() since it already
checks it.
The variables 'rar_low' and 'rar_high' represent the value in registers
RAL and RAH so we rename them to 'ral' and 'rah', respectively, to
match the registers names.
To make it explicit, filter settings are passed as arguments to the
function instead of reading them from adapter->mac_table "under the
hood". Also, the function was renamed to igc_set_mac_filter_hw to make
it more clear what it does.
Finally, the patch removes some wrfl() calls and comments not needed.

In fact, callers have extra code just to handle this returning
index as 0 (success).
So this patch changes the function to return 0 on success instead,
and cleans up the extra code.

This patch does a code refactoring in the MAC address filtering logic to
get rid of some duplicate code.
IGC driver has two functions to add MAC address filters that are pretty
much the same: igc_add_mac_filter() and igc_add_mac_filter_flags(). The
only difference is that the latter allows the callee to specify the
'flags' parameter while the former has it hard coded as zero. The same
rationale applies to filter deletion counterparts.
So this patch refactors igc_add_mac_filter() and igc_del_mac_filter() so
they handle the 'flags' parameters, removes the _flags() functions, and
fixes callees accordingly.

Pull flexible-array member conversion from Gustavo Silva:
"The current codebase makes use of the zero-length array language
extension to the C90 standard, but the preferred mechanism to declare
variable-length types such as these ones is a flexible array
member[1][2], introduced in C99:
struct foo {
int stuff;
struct boo array[];
};
By making use of the mechanism above, we will get a compiler warning
in case the flexible array does not occur last in the structure, which
will help us prevent some kind of undefined behavior bugs from being
inadvertently introduced[3] to the codebase from now on.
Also, notice that, dynamic memory allocations won't be affected by
this change:
"Flexible array members have incomplete type, and so the sizeof
operator may not be applied. As a quirk of the original
implementation of zero-length arrays, sizeof evaluates to zero."[1]
sizeof(flexible-array-member) triggers a warning because flexible
array members have incomplete type[1]. There are some instances of
code in which the sizeof operator is being incorrectly/erroneously
applied to zero-length arrays and the result is zero. Such instances
may be hiding some bugs. So, this work (flexible-array member
convertions) will also help to get completely rid of those sorts of
issues.
Notice that all of these patches have been baking in linux-next for
quite a while now and, 238 more of these patches have already been
merged into 5.7-rc1.

When the 'spi_device_id' table was removed, it omitted to cleanup/fix the
assignment:
'indio_dev->name = spi_get_device_id(spi)->name;'
After that patch 'spi_get_device_id(spi)' returns NULL, so this crashes
during probe with null de-ref.
This change fixes this by introducing an ad7192_chip_info struct, and
defines all part-names [that should be assigned to indio_dev->name] in a
'ad7192_chip_info_tbl' table.
With this change, the old 'st->devid' is also moved to be a
'chip_info->chip_id'. And the old 'ID_AD719X' macros have been renamed to
'CHIPID_AD719X'. Tld identifiers have been re-purposed to be enum/index
values in the new 'ad7192_chip_info_tbl'.
This should fix the bug, and maintain the ABI for the 'indio_dev->name'
field.

The XADC supports a samplerate of up to 1MSPS. Unfortunately the hardware
does not have a FIFO, which means it generates an interrupt for each
conversion sequence. At one 1MSPS this creates an interrupt storm that
causes the system to soft-lock.
For this reason the driver limits the maximum samplerate to 150kSPS.
Currently this check is only done when setting a new samplerate. But it is
also possible that the initial samplerate configured in the FPGA bitstream
exceeds the limit.
In this case when starting to capture data without first changing the
samplerate the system can overload.
To prevent this check the currently configured samplerate in the probe
function and reduce it to the maximum if necessary.

The XADC has two internal ADCs. Depending on the mode it is operating in
either one or both of them are used. The device manual calls this
continuous (one ADC) and simultaneous (both ADCs) mode.
The meaning of the sequencing register for the aux channels changes
depending on the mode.
In continuous mode each bit corresponds to one of the 16 aux channels. And
the single ADC will convert them one by one in order.
In simultaneous mode the aux channels are split into two groups the first 8
channels are assigned to the first ADC and the other 8 channels to the
second ADC. The upper 8 bits of the sequencing register are unused and the
lower 8 bits control both ADCs. This means a bit needs to be set if either
the corresponding channel from the first group or the second group (or
both) are set.
Currently the driver does not have the special handling required for
simultaneous mode. Add it.

When enabling the trigger and unmasking the end-of-sequence (EOS) interrupt
the EOS interrupt should be cleared from the status register. Otherwise it
is possible that it was still set from a previous capture. If that is the
case the interrupt would fire immediately even though no conversion has
been done yet and stale data is being read from the device.
The old code only clears the interrupt if the interrupt was previously
unmasked. Which does not make much sense since the interrupt is always
masked at this point and in addition masking the interrupt does not clear
the interrupt from the status register. So the clearing needs to be done
unconditionally.
