[PULL 1/3] ppc/pegasos2: Allow setprop in VOF

[David Gibson <david@gibson.dropbear.id.au>]

From: BALATON Zoltan <balaton@eik.bme.hu>

Linux needs setprop to fix up the device tree, otherwise it's not
finding devices and cannot boot. Since recent VOF change now we need
to add a callback to allow this which is what this patch does.
