Eero Nurkkala 8e43f39141 mpfs: cache: provide L1/L2 cache enablers
E51 may configure the L1 and L2 caches. Once configured,
no reconfiguration is possible after hardware reset is
issued.

L2 is 16-way set associative with write-back policy. The
size 2 MB, from which 1 MB is utilized with the values
provided here. That's a total of 8 ways. The rest of the
L2 is left out for the bootloader usage.

mpfs_enable_cache() first checks the bootloader usage
doesn't overlap with the cache itself, thus providing a
set of functional values.
