vc/google/chromeos: Move RAMOOPS region creation to BS_DEV_INIT_CHIPS

RAMOOPS memory region was being overwritten by coreboot bmp_load_logo()
function. The CBMEM_ID_FSP_LOGO region created during bmp_load_logo()
was overlapping with RAMOOPS space created earlier. This resulted in
memory corruption of RAMOOPS buffer.

To prevent this, the RAMOOPS region allocation is moved to
BS_DEV_INIT_CHIPS phase from earlier BS_WRITE_TABLES phase of boot.

BUG=b:332910298
TEST=build and boot coreboot image on google/rex HW. Check RAMOOPS
CBMEM region creation using cbmem -l command
