[RFC PATCH 04/11] omap4: SDP: Pass regulator_init_data from DT

[Rajendra Nayak]

Pass regulator_init_data 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().

Add documentation for TWL regulator specific bindings.
