intel/baytrail: use fmap information for code caching
Instead of using CBFS_SIZE from Kconfig, use values generated from fmap.
While at it, make sure that the cached region size is a power of two.
fmap_config is also added to cpu_incs-y, but that doesn't hurt (except
for some miniscule increase in compile time) because it's #if-guarded.
The upside is that dependencies are tracked properly.
