Apply cache-as-ram conditionally on socket mPGA604
The socket mPGA604 is for P4 Xeon which to my knowledge is always
HT-enabled. I assume the existing usage of car/cache_as_ram.inc
on socket_mPGA604, namely the Tyan S2735, as broken.
Existing car/cache_as_ram.inc has invalid SIPI vector and it does
not initialise AP CPU's to activate L2 cache.
Other mPGA604 boards are not affected, as they have not been
converted to CAR.
