This commit enables the support for K&P's HSC|DDC imx53 based boards. It was also necessary to provide device tree description for regulators to avoid board specific code definition. The GPIO pin description responsible for VBUS control has been moved from "hog" group to usbh1 dedicated one. Signed-off-by: Lukasz Majewski <lukma@denx.de>
