Introudce i.MX7 pinctrl driver support. For now only i.MX7D supported. There are two iomux controllers in i.MX7D, iomuxc and iomuxc_lpsr. To iomuxc_lpsr, ZERO_OFFSET_VALID is set, means offset of mux_reg and conf_reg can begin at 0. Signed-off-by: Peng Fan <van.freenix@gmail.com> Reviewed-by: Simon Glass <sjg@chromium.org>
