[PATCH 2/5] Documentation: mmc: sdhci-of-arasan: add power domain description

From: Shawn Lin
Date: Fri Jul 29 2016 - 00:19:02 EST

This patch adds power domain as a optional property for sdhci-of-arasan.
We should handle the power domain if available as it's in off
state due to the policy of power-saving after booting up. Otherwise
controller can not be accessed.
