mainboard/*/romstage.c: Sanitize system header inclusions

Fix system include paths to be consistent. Chipset support is
part of the Coreboot 'system' and hence 'non-local' (i.e., in
the same directory or context). One possible product of this, is
to perhaps allow future work to do pre-compiled headers (PCH) on
the buildbot for faster build times. However, this currently just
makes mainboard's consistent.
