No functional changes on this patch. Better organize the delivery
system information and data types, putting everything together,
to improve readability.

The driver were using a hacky way of setting analog and digital
frequencies. Remove the hack and properly add the tuner logic for
each supported type of standard.
I was tempted to add more standards there, like SECAM and to fix
radio (as stepping seems broken), but I opted to keep it as-is,
as tests would be needed to add additional standards.

Such code is disabled via ifdef's. Also, they're ugly and rely
on some static structures. Just remove. If ever needed, the git
log can be used to recover it.

Found an odd bug while implementing support for the HVR1850 that
lead to jerky video during the first capture, if the encoder was
not initialized early. I've modied the driver to configure the
encoder early, and this avoids the issue - a reasonable workaround.
Regression tested against the HVR1800 and soon to be added HVR1850

Bugfix: The height was not always correctly configured if switching between
different video standards. Change the encode height based on the standard.

During initialization the prior GPIO's were not being preserved
and restore correctly. Small cleanups to configure the GPIO's
for the HVR1700, HVR1800 and HVR1850.

Since the conversion to subdev in Oct 2010 the audio controls have
not functioned correctly in the cx23885 driver. Passing values of
0-3f did not translate into meaningfull register writes. I've
converted the cx23885 driver to match the cx25840 volume control
definition and now audio is working reliably again.

- enable fast usb quirk
- use usleep_range instead on msleep for short sleep
- merge i2c out and usb delay
- do like the windows driver that upload the tuner firmware
with 80 bytes packets

Now that this field is deprecated, and core generates it for
DVBv3 calls, remove it from the drivers.
It also adds .delsys on the few drivers where this were missed.

Mark info.type as deprecated inside the header, recommending
the usage of DTV_ENUM_DELSYS DVBv5 command instead.

This var were used during DVBv3 times, in order to keep a copy
of the parameters used by the events. This is not needed anymore,
as the parameters are now dynamically generated from the DVBv5
structure.
So, just get rid of it. That means that a DVBv5 pure call won't
use anymore any DVBv3 parameters.

For frontends with ISDB-T, DVB-T2, CMDBTH, etc, some code is
needed, in order to provide emulation. Add such code, and check
if the desired delivery system is supported by the frontend.

Get rid of using ops->info.type defined on DVB drivers,
as it doesn't apply anymore.
Currently, one driver (cxd2820) supports more than one different
info.type, as it can be used for DVB-T/T2 and DVB-C. There are more
drivers like that to come. So, the same frontend will have
different DVBv3 types, depending on the current delivery system.
This breaks the existing logic at dvb_frontend, that assumes that
just one delivery system DVBv3 type is supported by all delsys.
In order to easy the DVBv3->DVBv5 conversion, an ancillary function
that maps DVBv3 delivery systems into DVBv5 were added.
Also, on all places, except for the event logic, the DVBv5 cache
will be used to check parameters, instead of the DVBv5 copy.
This patch simplifies the cache sync logic, and warrants that the
cache will be in a clear state at DVB frontend register. This way,
ops->info.type will be filled to reflect the first delivery system,
providing backward compatibility support for it.
For example, in the cases like cxd2820, where the delivery systems
are defined as:
.delsys = { SYS_DVBT, SYS_DVBT2, SYS_DVBC_ANNEX_A },
A pure DVBv3 will be able to use both DVB-T and DVB-T2, as, at
DVB cache clear, the ops->info.type will be equal to FE_OFDM.
However, DVB-C won't be visible. A quick workaround would be to
do a DVBv5 call to set the delivery system to SYS_DVBC_ANNEX_A.
After such call, ops->info.type will be equal to FE_QAM, and a
DVBv3 application will see the frontend as a DVB-C one.

This change is there in order to prepare the code to avoid calling
dvb_frontend_ioctl_legacy() from FE_SET_PROPERTY.
A call to dvb_frontend_ioctl_legacy() would require to update the
DVBv3 cache without need, mangling calls for newer delivery system
without any reason.
No functional changes here.

Due to DVB-T2, several new possible values for bandwidth were added.
As the DVBv3 struct were updated to handle them, the core needs to
handle all of them, as a DVBv3 application might try to use it.

By default, initialize the frontend current delivery system with
the first one. This warrants that a DVBv3 application will be able
to tune to it, after the removal of ops->init.type filling at
the drivers.
