[ Upstream commit 25ef5b5d02ac03fe8dd91cf25bd011a570fbeba2 ]
Enable 160MHz beamformee support on mt7922 by updating HE capability element configuration. Previously, only 160MHz channel width was set, but beamformee for 160MHz was not properly advertised. This patch adds BEAMFORMEE_MAX_STS_ABOVE_80MHZ_4 capability to allow devices to utilize 160MHz BW for beamforming.
Tested by connecting to 160MHz-bandwidth beamforming AP and verified HE capability.
