superio/smsc/kbc1100: Virtually rewrite support and fix mainboards
1. Remove #include .c in romstage. 2. Make romstage component symbols linker-time. 3. Provide header guards and prototypes in superio romstage support. 4. Correct function type-signatures to be static/non-static where appropriate, avoid 'pretend optimisations' by unnecessarily inlining functions. 5. Separate out UART enable from various other PNP hard coding Change-Id: I9b8dad7c02d802e97db73ddf2913d5c6bb33a419 Signed-off-by: Edward O'Callaghan <eocallaghan@alterapraxis.com> Reviewed-on: http://review.coreboot.org/5916 Tested-by: build bot (Jenkins) Reviewed-by: Kyösti Mälkki <kyosti.malkki@gmail.com>
