drivers/wifi: Support Bluetooth Bands Selection Mode
This feature provides ability to provide Bluetooth Bands Selection
Mode. The bluetooth bands selection mode is defined as follow:
| Bit | Band GHz | Value | Description | Default |
|------+----------+-------+----------------------+---------|
| 0 | 2.4GHz | 0 | Controlled by NIC | 0 |
| | | 1 | Force disable 2.4GHz | |
| 1 | 5.2GHz | 0 | Controlled by NIC | 0 |
| | | 1 | Force disable 5.2GHz | |
| 2 | 5.8GHz | 0 | Controlled by NIC | 0 |
| | | 1 | Force disable 5.8GHz | |
| 3 | 6.2GHz | 0 | Controlled by NIC | 0 |
| | | 1 | Force disable 6.2GHz | |
| 31:4 | Reserved | | NA | 0 |
The implementation follows document 559910 Intel Connectivity
Platforms BIOS Guideline revision 9.2 specification.
