Subject: [PATCH v2 1/3] extcon: arizona: Add extcon specific device tree binding document

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
extcon specific bindings.
