Arthur Heymans 7875dbd981 cpu/intel/p4-netburst: skip caching rom on model_fxx 
An unidentified combination of speculative reads and branch
predictions inside WRPROT-cacheable memory can cause invalidation of
cachelines and loss of stack on models based on NetBurst
microarchitecture.

Therefore disable WRPROT region entirely for all family F models.

As an extreme example, just changing the location of a constant string
passed to printk() has been witnessed to make a the boot fail early on
in romstage.
