[PATCH 4/4] wifi: rtw89: advertise EHT OM Control for 8922a per WFA cert

[Louis Kotze <loukot@gmail.com>]

Wi-Fi Alliance Certificate WFA129313 (RTL8922AE, 2024-05-23, firmware
6102.24.109.0) certifies "Operating mode indication" as a Wi-Fi 7
feature for this chip. The driver currently sets only MAX_MPDU_LEN +
RESTRICTED_TWT in mac_cap_info[0], leaving EHT OM Control unset.

Set IEEE80211_EHT_MAC_CAP0_OM_CONTROL in mac_cap_info[0]. EHT OM
Control extends the HE OMI control mechanism (already advertised at
the HE layer) to EHT-specific operating-mode notifications. mt76
(mt7996, mt7925) and iwlwifi mvm + mld already set this single bit
for their Wi-Fi 7 STAs; hwsim sets it in test code.

Tested on RTL8922AU against TP-Link Deco BE63; assoc + EMLSR multi-
link state remain stable.
