omap_msdi_reset - reset the MSDI IP block : struct omap_hwmod *

The MSDI IP block on OMAP2420 has to have both the POW and CLKD fields set inside its CON register for a reset to complete successfully. This is not documented in the TRM. For CLKD, we use the value that results in the lowest possible clock rate, to attempt to avoid disturbing any cards.
