wil6210: Add EDMG channel support

Add support for Enhanced Directional Multi-Gigabit (EDMG) channels 9-11.
wil6210 reports it's EDMG capabilities (that are also based on FW
capability) to cfg80211 by filling
wiphy->bands[NL80211_BAND_60GHZ]->edmg_cap.
wil6210 handles edmg.channels and edmg.bw_config requested in connect
and start_ap operations.
