wifi: mac80211: allow advertising 20 MHz-only non-AP STA

Browse source

802.11 Clause 27 (HE) already defined a 20 MHz-only non-AP
HE STA in the 5 GHz band, where VHT is required, although
VHT in Clause 21 requires 20, 40 and 80 MHz support. The
VHT requirement is implemented in mac80211, but the later
allowance for 20 MHz-only since HE wasn't.

Allow a device to be a 20 MHz-only non-AP STA and require
that it support VHT, but not that it has 80 MHz support,
if it's HE as well.
