ASoC: omap-mcbsp: Enable/disable sidetone block auto clock gating for omap3

Browse source

OMAP3's McBSP2 and McBSP3 module have integrated sidetone block with
dedicated SYSCONFIG register. The sidetone is operating from the maain
McBSP module's ICLK. For normal operation the sidetone clock auto idle
support needs to be disabled when it is activated.
Note: This is not enough to avoid choppy sidetone because this AUTOIDLE
bit is controlling only the clock auto idle from the McBSP to the sidetone
block. If the McBSP_ICLK is idling, the sidetone clock is going to do the
same.
