[PATCH v2 1/6] mmc: omap_hsmmc: start using generic non-removable DT binding

From: Sekhar Nori <nsekhar@ti.com>

add generic "non-removable" binding support for omap_hsmmc.
When ti,non-removable was added, Only OMAP platform that had eMMC was that on
OMAP4 where power to eMMC cannot be switched off without sending CMD5 sleep
command, so no_regulator_off_init was needed to get it detected during boot.
Start using generic non-removable for all removable cards which do not
have such limitation.
