David Gibson a864a6b382 target/ppc: Streamline calculation of RMA limit from LPCR[RMLS] 
Currently we use a big switch statement in ppc_hash64_update_rmls() to work
out what the right RMA limit is based on the LPCR[RMLS] field.  There's no
formula for this - it's just an arbitrary mapping defined by the existing
CPU implementations - but we can make it a bit more readable by using a
lookup table rather than a switch.  In addition we can use the MiB/GiB
symbols to make it a bit clearer.

While there we add a bit of clarity and rationale to the comment about
what happens if the LPCR[RMLS] doesn't contain a valid value.
