Maybe the commit log could be better, but they are real bug fixes.

ARM: imx35 Bugfix admux clock

This patch registers a new lookup so that the audmux driver finds the
clock and enables it (the clock is optional in the driver). Otherwise
the clock framework will find the clock unused and disables it during
late init time.

ARM: clk-imx35: Bugfix iomux clock

This patch enables a clock needed for the iomuxer, otherwise it gets
disabled during late init time and the iomux stops working. This usually
is not noticed because normally the iomux is configured before that
point.
The really correct solution is to add clock support to the iomux driver
instead of enabling it in the SoC clock driver. This requires changes for
all SoCs using this driver though which still should be done later.
