[PATCH v4 1/4] regulator: dt-bindings: Add 'regulator-off-on-delay-us' property

[Jishnu Prakash]

Add a new property 'regulator-off-on-delay-us' to specify a minimum delay
between disabling and re-enabling a regulator. This is useful in cases
where a regulator discharges slowly and needs significant time to reach a
safe reset level, and re-enabling it too early may lead to a brownout
event.
