soc/qualcomm/x1p42100: Optimize memory layout for X1P42100

Browse source 
Refactor memory layout on x1p42100 to reuse a single reserved region
for all QC image metadata passed from coreboot to QcLib for TME
authentication. Also, reposition the PRERAM_CBMEM_CONSOLE reservation
after the QcLib region to allow for future expansion.

TEST=Successfully booted google/bluey.
