Subject: [PATCH v2] mmc: omap_hsmmc: Make use of the helper macro SET_RUNTIME_PM_OPS()

Use the helper macro SET_RUNTIME_PM_OPS() instead of the verbose
operators ".runtime_suspend/.runtime_resume", because the
SET_RUNTIME_PM_OPS() is a nice helper macro that could be brought
in to make code a little more concise.

v1->v2:	*Add "#ifdef CONFIG_PM" around runtime_suspend|resume().
	*Remove the unused implementation of omap_hsmmc_context_restore()
