KVM: PPC: allow ppc440gp to pass the compatibility check
Match only the first part of cur_cpu_spec->platform. 440GP (the first 440 processor) is identified by the string "ppc440gp", while all later 440 processors use simply "ppc440". Signed-off-by: Hollis Blanchard <hollis_blanchard@mentor.com> Signed-off-by: Alexander Graf <agraf@suse.de>
