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

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.
