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.

Most specific values always come first. Of course, this point is moot since "regulator" shouldn't be used at all.
+ +Optional properties: +- Any optional property defined in bindings/regulator/regulator.txt +- ti,reg-id: Identifier for a TWL regulator, defined in linux/i2c/twl.h file.
This needs more explanation. I don't understand what it means.
