mmc: omap_hsmmc: Fix Unbalanced pm_runtime_enable warning

Otherwise we can get following warning when re-loading the
omap_hsmmc driver module when gpio_twl4030 module is not
loaded:

omap_hsmmc omap_hsmmc.0: Unbalanced pm_runtime_enable!
omap_hsmmc omap_hsmmc.0: Unable to grab MMC CD IRQ
omap_hsmmc: probe of omap_hsmmc.0 failed with error -22

Kevin, maybe take a look and see if this is correct and
fits into your PM branches?
