[PATCH v2 2/3] regulator: arizona: Add regulator specific device tree binding document

[Charles Keepax]

Subystem specific bindings for the Arizona devices are being factored
out of the MFD binding document into seperate documents for each
subsystem. This patch adds a binding document that covers the existing
regulator specific bindings.
