[0/2] KVM: selftests: Add powerpc support

Message

This series adds the initial support for ppc64le Book3s with Radix
MMU.

At this time I'm including only the kvm_page_table test and a dummy
test to serve as a sample of what can be done with these tests. I
intend to make a pass over the remaining common tests and add the ones
which could be built for powerpc as well.

patch 1: a prerequisite small fix for the powerpc vcpu_ioctl. It is
         the same I already sent to the ppc mailing list but I'll
         include it here to make this a complete series.

patch 2: the actual infrastructure support.
