wifi: iwlwifi: mvm: cleanup unsupported phy command versions

The iwlmvm op mode is used for pre EHT HWs. Those HWs doesn't have wider
OFDMA, so phy command versions 5+ (that added support for wider OFDMA)
are not supported. Remove support for them.

This means that we also don't need to set the
IEEE80211_VIF_IGNORE_OFDMA_WIDER_BW, as we don't care about the ap
chandef anyway.
