Add support for ppag in China by reading revision 2 of the ppag table
from ACPI, and passing the data to the FW.
This is needed to enable OEMs to control ppag enablement
in China.

Add support for the new version of the GEO_TX_POWER_LIMIT command.
This new version includes UHB values in the table, but for now, since
we don't have the ACPI values yet, we support the API, but don't set
the extra values.

Add the version number to the iwl_geo_tx_power_profile_cmd structs and
move the union into a common place. Additionally, reuse the code that
sets elements that are at the same place in the struct across
different versions.
While at it remove an unused variable, add a comment and move the v2
specific element setting to inside the if statement. Additionally,
invert the if for slightly more readability.

The new version of the command can support more subbands and CDB, so
it can contain more data than earlier versions. Implement support for
the new version of the command, even though we don't have more data to
write to it yet.

Create a common structure to contain all different versions of the
tx_power_cmd instead of making a union of the different structs
everywhere we need them. Also move the common part of these structs
into a separate structure (instead of reusing v3) and leave the
per_chain_restriction part out of the common part, because this will
change in version 6 of the command (which will be added soon).
While at it, rename per_chain_restriction to per_chain to shorten it.

TX power limits as defined in the OTP assume the worst case scenario
in terms of the platform's atenna gain, but most platforms are below
that value so they can use more TX power without passing the regulatory
limit. If the platform indicates in the BIOS that it indeed has lower
gain, and the geographic location allows it, higher TX power can be
used. The driver reads the PPAG (Per-Platform Antenna Gain) data from
BIOS (if it exists), validates it and sends the appropriate command to
the FW. This flow happens once at FW init, in case of suspend/resume
there is no need to read again from BIOS as we save those values during
init, so just send the PPAG command again to FW.

South Korea is adding a more strict SAR limit called "Limb SAR".
Currently, WGDS SAR offset group 3 is not used (not mapped to any country).
In order to be able to comply with South Korea new restriction:
- OEM will use WGDS SAR offset group 3 to South Korea limitation.
- OEM will change WGDS revision to 1 (currently latest revision is 0)
to notify that Korea Limb SAR applied.
- Driver will read the WGDS table and pass the values to FW (as usual)
- Driver will pass to FW an indication that Korea Limb SAR is applied
in case table revision is 1.

In low power modes, the chip clock source for platform integrated
devices is 32kHz. It is generated internally and supplied by a crystal
oscillator. However using a 32kHz sourced from crystal oscillator
has high power penalty.
There is an option to get an external 32kHz clock from the platform. Past
experience shows that the reliability is platform dependent,
i.e. on some platforms it works good and on other it doesn’t.
Working from external clock will save 0.5 mW in sleep state, from overall
1.8mW that we have today, i.e. almost 30%.
Each OEM can enable or disable the use of the external 32kHz clock by
setting a BIOS configuration. In case the OEM configured to use 32kHz
external clock the driver will pass this indication to the FW.

Apart from DVM, all firmware uses the same base API, and there's
code outside iwlmvm that needs to interact with it. Reflect this
in the source better and reorganize the firmware API to a new
fw/api/ directory.
While at it, split the already pretty large fw-api.h file into a
number of smaller files, going from almost 3k lines in there to
a maximum number of lines less than 1k.
