] OMAP: HSMMC: Initialize hsmmc controller registers when

Most registers lose its state when the processor wakes up from sleep state.
Thus registers should be initialized, when the processor wakes up. However
the
current hsmmc 'resume' function doesn't consider this issue

Most registers lose its state when the processor wakes up from sleep state.
Thus registers should be initialized, when the processor wakes up. However the
current hsmmc 'resume' function doesn't consider this issue and finally makes
deadlock. So this patch fixes this problem.
