i.MX31: Fix mx31_gpio_mux() function and MUX_-macros.
Correct the mx31_gpio_mux() function to allow changing all i.MX31 IOMUX contacts instead of only the first 256 ones as is the case prior to this patch. Add missing MUX_* macros and update board files to use the new macros. Signed-off-by: Magnus Lilja <lilja.magnus@gmail.com>
