intel: Do not hardcode the position of mrc.cache
The reason for hardcoding the position of the MRC cache was to satisfy the alignment to the erase size of the flash chip. Hardcoding is no longer needed, as we can specify alignment directly. In the long term, the MRC cache will have to move to FMAP, but for now, we reduce fragmentation in CBFS. Note that soc/intel/common hardcoding of mrc.cache is not removed, as the mrc cache implementation there does not use CBFS to find the cache region, and needs a hardcoded address.
