If device-tree is present, then do not create the PMU device from within
the OMAP specific PMU code. This is required to allow device-tree to
create the PMU device from the PMU device-tree node.

PMU is not currently supported for OMAP4430 (due to a dependency on
having a cross-trigger interface driver) and so ensure that this
indicated on boot with or without device-tree.
