KVM: PPC: Add devname:kvm aliases for modules

Browse Source 
Systems that support automatic loading of kernel modules through
device aliases should try and automatically load kvm when /dev/kvm
gets opened.

Add code to support that magic for all PPC kvm targets, even the
ones that don't support modules yet.
