cpu/intel/microcode: allow microcode to be loaded in romstage
The previous usage of the intel microcode support supported using
the library under ROMCC and ramstage. Allow for microcode support
to be used in normal C-based romstage as well by:
1. Only using walkcbfs when ROMCC is defined.
2. Only using spinlocks if !__PRE_RAM__
The header file now unconditionally exposes the declarations
of the supporting functions.
