dmaengine: pl330: fix issues with big-endian armv7

Browse source

When running Xilinx Zynq in big-endian mode the pl330 driver
fails to pass the dmatest suite. To fix this, ensure all non
byte values are written in little endian.

As a note, the documentation does not mention if it will do
big-endian descriptor fetches, only that it will swap the
data in flight.
