According IEEE Std 802.11-2020, its definition is:
Indicates whether the STA is capable of interpreting the Extended NSS BW
Support subfield of the VHT Capabilities Information field.
Some APs, such as Xiaomi AX6000, would check this one for BW settings.
mt76 driver can get max BW capability only if the this field is confgured
properly.

In ACPI SAR enabled device, mt7921 should read power limit in ACPI config.
The limit value would be applied to regular tx power settings in mt76.
Two major functionalities added:
1. Get SAR power table through ACPI.
2. Read power in Dynamic/Geo SAR table for tx power limit.
Table note
MTDS: Dynamic SAR table
MTGS: Geo SAR table
MTCL: Country List table (for 6GHz support)
