mach-ux500: add MUSB to db8500 devices
- DMA tx and rx maps for usb channels are set to be configured at runtime - GPIO configurations for usb are added - MUSB is enabled with soc specific base address, irq and dma configurations Signed-off-by: Mian Yousaf Kaukab <mian-yousaf.kaukab@linaro.org> Signed-off-by: Linus Walleij <linus.walleij@linaro.org>
