[PATCH] remove ppc functions from callbacks

[Glauber Costa <glommer@redhat.com>]

handle_powerpc_dcr_read() and handle_powerpc_dcr_write() are two
powerpc specific functions that are called via libkvm callbacks.
However, grepping the source code finds simply no use of them. This
is probably due to the fact that powerpc now relies on a totally
qemu upstream implementation of kvm, and does not need it anymore.

Anyway, I'm providing this patch separatedly, so that if it breaks
for whenever reason, we can identify a bisection point easily
