mac80211: ath12k: fix regulatory range for wideband radios

Currently, trying to start a 5GHz radio on 8devices Kiwi will fail as
despite the phy listing the 5GHz channels in iw phy dump, no radio actually
claims the 5GHz range.

This is because driver assumes that if radio supports 6GHz then it cannot
be used for 5Ghz, this is however not correct for wideband radios.

So, similar to the 103-wifi-ath12k-fix-5GHz-operation-on-wideband-QCN.patch
patch ath12k_regd_update() so that 5Ghz range is listed as well.
