Add tsl2550 ambient light sensor DT data to am335x-evm.dts. In AM335x
EVM tsl2550 ambient light sensor is connected to I2C2 bus. So this patch
adds child node inside i2c2 node with i2c slave address.
TAOS tsl2550 sensor with two-wire SMBus serial interface. This patch
also reduces I2C2 clock frequency to 100KHz from 400KHz because the
maximum clock frequency of SMBus is 100KHz.
