[PATCH v3 2/4] regulator: arizona: Add regulator specific device tree binding document

[Charles Keepax <ckeepax@opensource.wolfsonmicro.com>]

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

Signed-off-by: Charles Keepax <ckeepax@opensource.wolfsonmicro.com>

Changes since v2:
 - Moved the core regulators back into the MFD component
 - Moved the maintainer updates into a separate patch

Thanks,
Charles
