[WIP]cpu/intel/socket_mPGA604: Run romstage from CAR

With a pentium 4 CPU running WP XIP is not possible. To speed up
execution copy romstage to CAR.

With a default build stack + other symbols take up 0x2e50 bytes, so
increase the CAR region, which must be a power of 2 and set
ROMSTAGE_ADDR at a comfortable distance.

TEST: Does compressing ROMSTAGE, speed up things even more?
