This registers the PL022 PrimeCell from the U300 device
tree. We make a new copy of the platform data for the
device tree boot path, as the old platform data is in an
older file which will be going away.

Why do you need both the platform data and the DT description?

This is because the device-tree DMA support for PL022 has
not yet been merged upstream, so it still has to come from
platform data instead.

If/when there is a branch in ARM SoC that has that patch in place
(and I remember reviewing and ACKing it) I can rebase on that
and drop the platform data.

The same goes for PL011 and MMCI platform data actually...
