Currently the getting and setting of Power MMU registers (sregs) take up
large inline chunks of the kvm_arch_get_registers() and
kvm_arch_put_registers() functions. Especially since there are two
variants (for Book-E and Book-S CPUs), only one of which will be used in
practice, this is pretty hard to read.
This patch splits these out into helper functions for clarity. No
functional change is expected.
