I'm going to start looking at the UART1 pinctl that Andrew mentioned 

v3:
Changed fmc compatible string to use "aspeed,ast2400-fmc" as per review

v2:
Rebased patch on the openbmc github dev-4.7 branch
Removed commented out eeprom
Removed of_machine_is_compatible for LPC/UART config
checkpatch whitespace fixup
