intel CAR: Fix DCACHE_RAM_BASE for old sockets

When using fixed MTRRs for CAR setup, CONFIG_DCACHE_RAM_BASE is ignored
and was not correctly set on affected sockets and boards. It was still
referenced in romstage linker script. This was discovered by clang builds
failing for cases where DCACHE_RAM_BASE = 0, while gcc builds passed.

The actual DCACHE_RAM_BASE programming is base = 0xd0000 - size, as taken
from intel/cpu/cache_as_ram.inc.
