soc/intel/cmn/block/cse: Create CBMEM entries for payload to fill with CSE info

Currently, the payload cannot create new CBMEM entries as there is
no such infrastructure available. The Intel CSE driver in the payload
needs below CBMEM entries -

1. CBMEM_ID_CSE_INFO to -
  a. Avoid reading ISH firmware version on consecutive boots.
  b. Track state of PSR data during CSE downgrade operation.

2. CBMEM_ID_CSE_BP_INFO to avoid reading CSE boot partition
information on consecutive boots.

The idea here is to create required CBMEM entries in coreboot so
that later they can be consumed by the payload.

BUG=b:305898363
TEST=Store CSE version info in CBMEM area in depthcharge on Screebo
