wifi: rtw88: Add missing VID/PIDs for 8811CU and 8821CU

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.
