ARM: clk-imx35: Bugfix iomux clock
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.
