This series of patches is meant to add support for USB Mass Storage on SAM9X60, SAMA7G5 and SAMA5D2 boards and register ohci-at91 driver into Driver Model. In order for this to be achieved, the respective DT nodes have been added, the USB clock has been registered into CCF and the required defconfigs have been added to the boards' defconfig. What is more, in order for the VBUS to stay enabled, a `child_pre_probe` method has been added to overcome the DM core disabling it in `usb_scan_device`: when the generic `device_probe` method is called, the pinctrl is processed once again, undoing whatever changes have been made in our driver's probe method. In order to enable USB on SAMA7G5 the addition of RSTC and USB 2.0 PHY drivers were required.
