wifi: mt76: mt7925: add EHT control support based on the CLC data

Some countries do not support EHT modulation for now. To prevent violating
regulations, the MT7925 chipset should control the EHT capabilities.
Therefore, when a regulatory domain change is detected during scanning,
the `mt7925_regd_be_ctrl` will process the CLC data to update the EHT
capabilities.
