[PATCH 1/2] regulator: dt-bindings: add regulator-state-standby bindings

[Andrei.Stefanescu]

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.
