soc/intel/common/cache_as_ram.S: Add macro to find a free MTRR
This adds a macro to find an available MTRR(s) to set up CAR.
This added complexity is not required on bootpaths without bootguard
but with bootguard MTRR's have already been set up by the ACM so
we need to figure out at runtime which ones are available.
