KVM: PPC: Move processor compatibility check to module init
Move KVM PPC's compatibility checks to their respective module_init()
hooks, there's no need to wait until KVM's common compat check, nor is
there a need to perform the check on every CPU (provided by common KVM's
hook), as the compatibility checks operate on global data.
arch/powerpc/include/asm/cputable.h: extern struct cpu_spec *cur_cpu_spec;
arch/powerpc/kvm/book3s.c: return 0
arch/powerpc/kvm/e500.c: strcmp(cur_cpu_spec->cpu_name, "e500v2")
arch/powerpc/kvm/e500mc.c: strcmp(cur_cpu_spec->cpu_name, "e500mc")
strcmp(cur_cpu_spec->cpu_name, "e5500")
strcmp(cur_cpu_spec->cpu_name, "e6500")
