[PATCH mmotm/next] powerpc: fix powernv boot breakage on G5???

My PowerMac G5 cannot boot mmotm these days: different symptoms
(starting /sbin/init failed? or ATA errors and hang?), with unrelated
bugs adding to the confusion; but a bisection led to b5ff4211a829
"powerpc/book3s: Queue up and process delayed MCE events".  Since that
series seems to be mostly about powernv, I tried changing BOOK3S_64
to POWERNV in entry_64.S, which has got it back to working for me.

just in case this happens to be right, but it's well beyond me!
