soc/intel/xeon_sp/cpx: Align coreboot CAR symbols to FSP-T 

The CAR set up by FSP-T is at base 0xfe800000 and has a 0x200000 size.
FSP-M seems to have a very large stack usage so it would overflow
other car symbols located below the coreboot stack such as timestamps
and the pre-ram console, which are now fixed.

TEST: boot with ocp/deltalake.
