Convert PM operations to use dev_pm_ops. This will facilitate
the runtime PM coversion which will add to dev_pm_ops hooks.
Note that dev_pm_ops version of the suspend hook no longer takes a
'state' argument. However, the MMC core function mmc_suspend_host()
still takes a 'state' argument, but it is unused, so a dummy
state variable was created to pass to the MMC core.
In the future, the MMC core should be converted to drop this
state argument and the rest of the MMC drivers could be easily
converted to dev_pm_ops as well.
