omap3: cm-t35: add mux initialization
CM-T35 can be assembled with different set of peripherals thus making certain interfaces available to user as GPIOs or dedicated pins. Because of it CM-T35 bootloader sets up mux configuration only for pins necessary to boot the system and the rest of the mux configuration is done by the kernel. Besides, having mux configuration in the kernel allows to minimize dependancy on bootloader.
