soc/intel/cannonlake: Use EBDA area to store cbmem_top address
This patch uses BIOS EBDA area to store relevent details
like cbmem top during romstage after MRC init is done.
Also provide provision to use the same EBDA data across
various stages without reexecuting memory map algorithm.
BRANCH=none
BUG=b:63974384
TEST=Ensures HW based memmap algorithm is executing once in romstage
and store required data into EBDA for other stage to avoid redundant
calculation and get cbmem_top start from EBDA area.
