src/soc/intel/common: Make top_of_ram till TOLUD region mmio_resource
Ideally don't need to mark the entire top_of_ram till TOLUD range (used
for stolen memory like GFX and ME, PTT, DPR, PRMRR, TSEG etc) as
cacheable for OS usage as coreboot already done with mpinit w/ smm
relocation early.
TEST=Able to build and boot ICL, TGL RVP.
