ARM: liteboard: move towards driver model and device-tree boot

This patch mostly enables DM drivers in board defconfig and all their
dependencies. Additionally we remove USB code that is on longer
executed after enabling CONFIG_DM_USB. Enable CONFIG_PINCTRL, so we
can get rid of ethernet pin configuration.
