ASoC: mx27vis: retrieve gpio numbers from platform_data
Rather than including mach/iomux-mx27.h to define gpio numbers and set up the pins, the patch moves all these into machine code and has the gpio numbers passed to driver via platform_data. As the result, we can remove the mach/iomux-mx27.h inclusion from driver.
