wifi: iwlwifi: regulatory: support a new command for PPAG

Browse source 
Per Platform Antenna Gain is getting support for UNII-9.
Add a new version of PER_PLATFORM_ANT_GAIN_CMD.
This requires to increase the number of subbands in the firmware runtime
object.
Pass the number of subbands to iwl_bios_print_ppag to avoid printing
invalid values.

Introduce BIOS_PPAG_MAX_SUB_BANDS_NUM to avoid impacting
BIOS_SAR_MAX_SUB_BANDS_NUM which was used until now for PPAG as well.
SAR will get support for the new subband in future patches.

While at it, print the PPAG table as it was read from BIOS.
