drivers/wifi: Support Bluetooth Regulator Domain Settings
The 'Bluetooth Increased Power Mode - SAR Limitation' feature provides
ability to utilize increased device Transmit power capability for
Bluetooth applications in coordination with Wi-Fi adhering to product
SAR limit when Bluetooth and Wi-Fi run together.
This commit introduces a `bluetooth_companion' field to the generic
Wi-Fi drivers chip data. This field can be set in the board design
device tree to supply the bluetooth device for which the BRDS function
must be created.
This feature is required for Meteor Lake rex karis variant.
The implementation follows document 559910 Intel Connectivity
Platforms BIOS Guideline revision 8.3 specification.
BUG=b:348345301
BRANCH=firmware-rex-15709.B
TEST=BRDS method is added to the CNVW device and return the data
supplied by the SAR binary blob
