kvm: arm: Get rid of functions which just wrap the subclasses version.

The MuxingKvmGic class defined a few functions related to checkpointing which
did nothing other than call the underlying Pl390 implementation. These are
unnecessary in general, and are particularly unnecessary for the loadState
function which is a very lightly used part of the checkpointing interface.
It's not actually defined in Pl390 either, and falls through to the
underlying implementation.
