[PATCH 08/11] ARM: OMAP3: Remove callback for McBSP sidetone ICLK workaround

[Peter Ujfalusi]

We can achieve the same result with SIDLEMODE field within McBSP SYSCONFIG
register.
The ASoC driver has been modified to use this method and we can now remove
the workaround using the control module register.
