Benjamin Berg 2f2a09eb89 wifi: mac80211: do not permit 40 MHz EHT operation on 5/6 GHz 
commit 75575e2d252afb29fdbcbeec4d67e042007add52 upstream.

The EHT PHY requirements state that 80 MHz must be supported on the 5
and 6 GHz bands unless the STA is 20 MHz only. So if the channel width
is limited to 40 MHz on a band other than 2.4 GHz, then disable EHT and
downgrade to HE.

The primary case where this can happen is if the hardware disables
puncturing using IEEE80211_HW_DISALLOW_PUNCTURING.
