The efuse of the SDIO RTL8822BS chip has only one known member: the mac
address is at offset 0x11a. Add a struct rtw8822bs_efuse describing this
and use it for copying the mac address when the SDIO bus is used.

changes from v1 -> v2:
- remove extra newline which was added by accident in the USB function
- add the new function/union member/case statement last (after USB)
- while here, also sort the union members to be consistent with
the switch case (PCIe first, USB second, SDIO last)
