Add device tree data for tps65217 regulator by adding all tps65217
regulator nodes. Regulator is initialized based on compatiable
name provided in tps65217 DT file.

All tps65910 PMIC regulator device tree nodes are placed in a
seperate device tree include file (tps65217.dtsi). This patch
was tested on AM335x-Bone.
