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.
