drivers/wifi: Support Wi-Fi 7 11be Enablement

Browse source 
Add 802.11be (aka. Wi-Fi 7) enable/disable support based on document
559910 Intel Connectivity Platforms BIOS_Guidelines revision 8.3.

There are countries where Wi-Fi 7 should be disabled by default. This
adds capability for OEM to enable or disable by updating the board
specific Specific Absorption Rate (SAR) binary.

BUG=b:348345300
BRANCH=firmware-rex-15709.B
TEST=SSDT dump shows that the _DSM method returns the value supplied
     by the SAR binary for function 12
