The clock code
This patch enables iomuxc_gate clock. It is necessary to be able to reconfigure iomux pads. Without this clock enabled, the clk_disable_unused function will disable this clock and the iomux pads are not configurable anymore. This happens at every boot. After a reboot (watchdog system reset) the clock is not enabled again, so all iomux pad reconfigurations in boot code are without effect. The iomux pads should be always configurable, so this patch always enables it.
