Add device tree data for tps65910 regulator by adding all the consumers necessary for AM335X-EVM. The data will be map to a regulator constraints which is required for regulator set_voltage and get_voltage calls. All tps65910 PMIC regulator constraints are placed in a seperate device tree include file (tps65910.dtsi). This patch also adds the I2C slave address of TPS65910 pmic to am335x-evm.dts file.
