arm/dts: Add tps65217 regulator DT data to am335x-bone.dts

Add tps65217 regulator device tree data to AM335x-Bone by adding
regulator consumers with tightened constraints and regulator-name.
TPS65217 regulator handle can be obtained by using this regulator
name.

This patch also add I2C node with I2C frequency and tps65217 PMIC
I2C slave address.
