drivers/wifi: Support Bluetooth Per-Platform Antenna Gain
The ACPI BPAG method provide information to controls the antenna gain
method to be used per country.
The antenna gain mode is a bit field (0 - disabled, 1 -enabled)
defined as follow:
- Bit 0 - Antenna gain in EU
- Bit 1 - Antenna gain in China Mainland
The implementation follows document 559910 Intel Connectivity
Platforms BIOS Guideline revision 9.2 specification.
BUG=b:346600091
TEST=BPAG method is added to the bluetooth companion device and return
the data supplied by the SAR binary blob
