This commit adds support for setting VHT parameters based on the declared
VHT capability bits in the VHT capability structure.

The bit-field TX-BF is purposefully left out since wcn3680 is the only
wcn36xx that can do VHT/80211.ac and is not TX beamformer capable. TX-BF is
a dead bit.

Similarly we cannot do 160MHz so VHT Channel width set should be zero.
