[PATCH 2/3] omap4: sdp: Pass regulator data from dt

[Rajendra Nayak]

Pass adjustable regulator information for omap4sdp from device tree so the
regulator driver can then use the regulator helper
routine to extract and use them during the driver probe().

Also add documentation for TWL regulator specific bindings.
