powerpc: Fix setting of oprofile cpu type

commit 2657dd4e301d4841ed67a4fac7d145ad8f3e1b28 introduced a
bug where we would now always override the "real" oprofile CPU
type with the "compatible" one provided by a pseudo-PVR in the
device-tree which is incorrect and breaks oprofile on all current
configs since the "compatible" ones aren't yet recognized.

This fixes it.
