ARM: mxs: add helper macro for pad control
This patch is to add pad control helper macro to make the code easy to read. The need is being seen when adding pad definitions for LCDIF which gets ~30 pads to define. Signed-off-by: Shawn Guo <shawn.guo@freescale.com> Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>
