[PATCH] powerpc/85xx: Fix doorbells

[Matthew McClintock]

Commit 765342526246c97600e5344c0949824d94bb51c3 made some small
changes to IPI, message_pass in smp_ops was initialized to NULL
for other platforms but not for 85xx which causes us to always
use the mpic for IPI's. This patch makes doorbells work again.
