wifi: iwlwifi: acpi: add support for PPAG rev5
This adds support for UNII9 which requires to add a subband.
Just increase the number of subbands that we need to read.
Replace the usage of the IWL_NUM_SUB_BANDS_VX macros in acpi.h since
those macros are defined in the firmware API and ACPI declarations have
nothing to do the firmware API.
