superio/fintek: Add required changes so F81216H can be used
The amd/lamar mainboard is the first mainboard to use the f81216h. These changes are needed to fix up commit 27a63d77 so the Super I/O builds and functions correctly. - Wrong #include name - Removed global variable in romstage - Missing "case" in switch() Change-Id: I1b2058a915b776664fba14e4341e8a410b50330f Signed-off-by: Dave Frodin <dave.frodin@se-eng.com> Reviewed-on: http://review.coreboot.org/8255 Tested-by: build bot (Jenkins) Reviewed-by: Alexandru Gagniuc <mr.nuke.me@gmail.com>
