ARM: ux500: Create a new of_dev_auxdata structure for u8540 enablement
If we attempt to use the existing u8500 of_dev_auxdata struct to boot the u8540, we fail to obtain a console, due to a lack of DMA support on the platform. Signed-off-by: Lee Jones <lee.jones@linaro.org> Signed-off-by: Linus Walleij <linus.walleij@linaro.org>
