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

Browse Source 
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.

: equivalent with standby Linux sleep state, which provides energy savings
with a relatively quick transition back time.

: 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,
but includes a final step of writing memory contents to disk.
