wifi: iwlwifi: nvm: Update HE capabilities on 6GHz band for EHT device
Max A-MPDU length exponent shall be set to 2 for EHT capable
device on 6GHz band in order to support 4MB aggregation.
Update HE MAC capabilities accordingly for station and softap
interfaces.
This change requires to add another ieee80211_sband_iftype_data for
uhb since high/uhb are no longer the same.
