arch/x86: Always compile postcar library in romstage

Browse Source 
postcar_loader.c has a useful library of funtions for
setting up stack and MTRRs. Make it available in romstage
irrespective of CONFIG_POSTCAR_STAGE for use in stack setup
after Dram init.

The final step of moving the used and max MTRRs on to stack
is moved to a new function, that can be used outside of
postcar phase.
