arm64: add 'runtime constant' support
This implements the runtime constant infrastructure for arm64, allowing
the dcache d_hash() function to be generated using as a constant for
hash table address followed by shift by a constant of the hash index.
[ Fixed up to deal with the big-endian case as per Mark Rutland ]
