soc/intel: skl,cnl,icl: rely on TOLUM as cbmem_top returned by FSP
Instead of doing our own calculations, rely on TOLUM returned by FSP
for cbmem_top. This (hopefully) saves us from making mistakes in weird
calculations of offsets and alignments.
Further this makes it easier to implement e.g. SGX PRMRR size selection
via Kconfig as we do not have to make any assumptions about alignments
but can simply pass (valid) values to FSP.
