Subject: [PATCH v1 01/15] dt-bindings: add pwrseq device tree bindings

Add device tree bindings for the new power sequencer subsystem.
Consumers would reference pwrseq nodes using "foo-pwrseq" properties.
Providers would use '#pwrseq-cells' property to declare the amount of
cells in the pwrseq specifier.
