drivers/intel/fsp2_0/memory_init: Wrap calls into FSP
Use a wrapper code that does nothing on x86_32, but drops to protected
mode to call into FSP when running on x86_64.
Tested on Intel Skylake when running in long mode. Successfully run the
FSP-M which is compiled for x86_32 and then continued booting in
long mode.
