You remove the ab8500_device registration from snowball but add the prcmu and ab8500
in a place that is common to all three machines, so they will show up twice
on mop500 and hrefv60. If those two are not broken before this patch, I think
they are after it.

I think the two options you have here are to either remove the ab8500 device from
mop500_platform_devs[] too (essentially registering mop500_gpio_keys_device
and ab8500_device separately when you need them, instead of doing the loop),
or to split u8500_local_bus_nodes so you use a different table for snowball
from the one you use for the other boards.
