Makefile.inc: Optimize generating the default x86 fmap
Put the FMAP FMAP region right above the coreboot CBFS region.
The other regions like RW_MRC_CACHE and CONSOLE often have alignment
requirements so it makes sense to put those on top. This also
simplifies the code the generate the default fmap a little.
