[PATCH v2 1/3] nl80211: retrieve EHT capabilities in AP mode

[Aloka Dixit <quic_alokad@xxxxxxxxxxx>]

From: Vikram Kandukuri <quic_vikram@xxxxxxxxxxx>

Add support to retrieve the EHT capabilities element passed by
the userspace in the beacon template and store the pointer in
struct cfg80211_ap_settings to be used by MAC80211.
