Rename ti-omap5-opp-supply to be bit more generic omap-opp-supply and
convert the binding to yaml.

The 3rd example doesn't add anything. It's just different values.

As I recollect (been a while), it was variant per device. Did you have
something in mind or a reference for me to look at?

-Texas Instruments OMAP compatible OPP supply description
-
-OMAP5, DRA7, and AM57 family of SoCs have Class0 AVS eFuse registers which
-contain data that can be used to adjust voltages programmed for some of their
-supplies for more efficient operation. This binding provides the information
-needed to read these values and use them to program the main regulator during
-an OPP transitions.
-
-Also, some supplies may have an associated vbb-supply which is an Adaptive Body
-Bias regulator which much be transitioned in a specific sequence with regards
-to the vdd-supply and clk when making an OPP transition. By supplying two

-of the multi regulator binding that is part of the OPP core described here [1]
-to describe both regulators needed by the platform.
-
-[1] Documentation/devicetree/bindings/opp/opp-v2.yaml
-
-Required Properties for Device Node:
-- vdd-supply: phandle to regulator controlling VDD supply
-- vbb-supply: phandle to regulator controlling Body Bias supply
-	      (Usually Adaptive Body Bias regulator)
-
-Required Properties for opp-supply node:
-- compatible: Should be one of:
-	"ti,omap-opp-supply" - basic OPP supply controlling VDD and VBB
-	"ti,omap5-opp-supply" - OMAP5+ optimized voltages in efuse(class0)VDD
-			    along with VBB
-	"ti,omap5-core-opp-supply" - OMAP5+ optimized voltages in efuse(class0) VDD
-			    but no VBB.
-- reg: Address and length of the efuse register set for the device (mandatory
-	only for "ti,omap5-opp-supply")
-- ti,efuse-settings: An array of u32 tuple items providing information about
-	optimized efuse configuration. Each item consists of the following:
-	volt: voltage in uV - reference voltage (OPP voltage)
-	efuse_offseet: efuse offset from reg where the optimized voltage is stored.
-- ti,absolute-max-voltage-uv: absolute maximum voltage for the OPP supply.

-
-/* Device Node (CPU)  */
-cpus {
-	cpu0: cpu@0 {
-		device_type = "cpu";
-
-		...
