2024-04-03wifi: rtw89: 8922a: download template probe requests for 6 GHz bandPo-Hao Huang
8922a FW supports RNR parsing, provide template probe requests and let FW do the replacement for SSID/BSSID/short SSIDs. Don't declare WIPHY_FLAG_SPLIT_SCAN_6GHZ so proper IEs such as 6 GHz capabilities can be passed down within the same scan request.

This version of the chip requires loading an extra AGC table right after the main one, but the extra table is being loaded at the wrong time, in rtw_chip_board_info_setup(). Move the extra AGC table loading to the right place, in rtw_phy_load_tables(). The rtw_chip_board_info_setup() can only do "software" things, and rtw_phy_load_tables() can really do IO.

RTL8822CU, RTL8822BU, and RTL8821CU need an extra register write after reading and writing certain addresses. Without this, the firmware upload fails approximately more than 50% of the time.

Add VID/PIDs that are known to be missing for this driver. Removed /* 8811CU */ and /* 8821CU */ as they are redundant since the file is specific to those chips. Removed /* TOTOLINK A650UA v3 */ as the manufacturer. It has a REALTEK VID so it may not be specific to this adapter. Verified and tested.
