drivers/intel/fsp2_0: Enable XIP romstage with loaded FSP-M
Separate NO_XIP_EARLY_STAGES from loading FSP-M into cache-as-RAM.
Quark executes romstage directly from the SPI flash part (in-place),
but loads FSP-M into ESRAM. This split occurs because ESRAM is too
small to hold everything while debugging.
Platforms executing FSP-M directly from the SPI flash need to select
FSP_M_XIP.
TEST=Build and run on Galileo Gen2.
