mach-ux500: config Ux500 PL011 PL022 PL180 for DMA
This will configure the platform data for the PL011, PL022 and PL180 (derivate) PrimeCells found in the Ux500 to use DMA with the generic DMA engine for DMA40. Signed-off-by: Per Forlin <per.forlin@linaro.org> Signed-off-by: Linus Walleij <linus.walleij@linaro.org>
