mb/intel/ptlrvp: Add PTL-P RVP and GCS board IDs

This commit introduces new board ID definitions for PTL-P and GCS in the
PTLRVP mainboard code. The changes involve updating the `romstage.c` and
`memory.c` files to handle these new board IDs, ensuring that memory
configuration is correctly initialized based on the detected board
type.
