Subject: [PATCH 2/3] ARM: OMAP2+: AM33XX: Add tps65217 device tree data

Add device tree data for tps65217 regulator by adding all the consumers
necessary for AM335X-BeagleBone. The data will be map to a regulator
constraints which is required for regulator set_voltage and get_voltage
calls.

All tps65217 PMIC regulator constraints are placed in a seperate device
tree include file (tps65217.dtsi).

This patch also adds the I2C slave address of TPS65217 pmic to
am335x-bone.dts file.
