rtw88: 8821c: support RFE type4 wifi NIC

RFE type4 is a new NIC which has one RF antenna shares with BT.
RFE type4 HW is the same as RFE type2 but attaching antenna to
aux antenna connector.

RFE type2 attach antenna to main antenna connector.
Load the same parameter as RFE type2 when initializing NIC.
