ca7966c88e iwlagn: implement synchronous firmware load
The current firmware loading mechanism in
iwlwifi is very hard to follow, and thus
hard to maintain. To make it easier, make
the firmware loading synchronous.

For now, as a side effect, this removes a
number of retry possibilities we had. It
isn't typical for this to fail, but if it
does happen we restart from scratch which
this also makes easier to do should it be
necessary.

e46f6538c2 iwlagn: simplify error table reading
The current code to read the error table header
just hardcodes all the offsets, which is a bit
hard to understand. We can read in the entire
header (as much as we need) into a structure,
and then take the data from there, which makes
it easier to understand. To read a bigger blob
we also don't need to grab NIC access for each
word read, making the code more efficient.

0da0e5bf15 iwlagn: clean up & autodetect statistics
There's no need to keep both normal and BT statistics
versions around all the time in memory when we only
use a subset of both. So keep only the subsets that
we need in memory, depending on the debug config).

Also, in doing so, we can remove all the calls to
iwl_bt_statistics() in the driver as we'll just
access the copied statistics now.

Finally, also remove this call from the one place
where it might still be needed and automatically
detect what kind of statistics the device is sending
based on their size. This way, we don't need to keep
track of which devices do what any more, which is
good since this is subject to change based on the
ucode version (as some ucode even for non-BT devices
will in fact use BT statistics).

Warn upon encountering a statistics command from the
ucode that isn't known, so we will find such issues
earlier in the future.

d7d5783c66 iwlagn: clean up alive handling
Devices newer than 4965 don't actually send
two different versions of the ALIVE command,
so we always had a bug here since before this
patch we copy more data than we got. Remove
the iwl_init_alive_resp struct and don't use
it.

Since we also really don't need to track all
the data received in ALIVE as we only use the
error and log event tables later, we can also
save space by just keeping those and not more
data around in memory.

6000g2 devices need to have temperature offset calibration. The runtime
uCode needs to receive the calibration results just like BB and LO

642454cc07 iwlagn: fix default calibration table size
iwlagn driver uses the IWL_MAX_STANDARD_PHY_CALIBRATE_TBL_SIZE
as the chain noise reset calibration index and
IWL_MAX_STANDARD_PHY_CALIBRATE_TBL_SIZE+1 as the chain noise gain
calibration index, if not specified by the TLV value in the new
firmware format.

However, this is broken if we need to add more calibrations like
the temperature offset calibration because we increased
IWL_MAX_STANDARD_PHY_CALIBRATE_TBL_SIZE by 1.

To fix this issue, define IWL_DEFAULT_STANDARD_PHY_CALIBRATE_TBL_SIZE
and use it as the calibration index instead. We still keep the
IWL_MAX_STANDARD_PHY_CALIBRATE_TBL_SIZE as a sanity check for
the TLV value given by ucode.

6d6a1afdc5 iwlwifi: send DC calib config to runtime ucode
Since uCode is responsible for doing DC calibration, there's no need
to let init uCode to do initial DC calibration then send results
back to driver, then driver sends the results to runtime uCode.
Driver can simply tell runtime uCode to do DC calibration.

Actually, this patch does not disable DC calib for init uCode. It just
prevent driver from saving and sending the DC calib results (from init
ucode) to runtime uCode. The driver still uses 0xffffffff in
CALIB_CFG_CMD for init ucode.
