regulator: dt-bindings: add regulator-state-standby bindings 



For state-mem and state-disk regulators can have
various parameters applied such as enabled/disabled,
current mode, voltage etc.

This patch adds documentation on how to set these parameters
in the device tree for the standby state.

  : suspend to memory, the device goes to sleep, but all data stored in memory,

  only some external interrupt can wake the device.

  : suspend to disk, this state operates similarly to Suspend-to-RAM,

	- regulator-off-in-suspend: regulator should be off in suspend state.

	- regulator-suspend-min-microvolt: minimum voltage may be set in
