wifi: mt76: fix 5 GHz connection regression on mt76x0/mt76x2

Browse source 
Some users have reported being unable to connect to MT76x0 APs running mt76
after a commit enabling the VHT extneded NSS BW feature.
Fix this regression by ensuring that this feature only gets enabled on drivers
that support it
