powerpc/64/kexec: Fix MMU cleanup on radix
Just using the hash ops won't work anymore since radix will have NULL in there. Instead create an mmu_cleanup_all() function which will do the right thing based on the MMU mode. For Radix, for now I clear UPRT and the PTCR, effectively switching back to Radix with no partition table setup. Currently set it to NULL on BookE thought it might be a good idea to wipe the TLB there (Scott ?)
