mainboard/asus/[kgpe-d16|kcma-d8]: Enable secondary serial port header
The ASUS KGPE-D16/KCMA-D8 have an on-board header for a second RS-232
serial port, however it is disabled by default due to the SuperIO
default pin mux settings. Enable the secondary serial port early
in romstage to allow use during / after initial boot.
