Sorry, that patch wasn't much good. This one I have really tested properly
and checked that the 'put' match the 'get's and that the device to regularly
go to sleep as expected.

Subject: [PATCH] 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.
