Subject: [PATCH 1/2] mmc: omap_hsmmc: stop using .enable and .disable method.

enable and disable are only used to get and put
runtime pm references.  .set_ios already does this
itself, and other drivers just do it in set_ios
and .request without using enable/disable.

So add pm_runtime get/put to omap_hsmmc_request(),
and discard the enable/disable methods.
