soc/intel/cannonlake: Calculate soc reserved memory size

This patch implements soc override function to calculate reserve memory
size (PRMRR, ME stolen, PTT etc). System memory should reserve those
memory ranges.

BRANCH=none
BUG=b:63974384
TEST=Ensures DRAM based resource allocation has taken care
of intel soc reserved ranges.
