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.

Hi Tony/Benoit,

If there are no comments in this patch could you please take this in?

Have you updated the binding documentation to list the device?

It should be in:
Documentation/devicetree/bindings/i2c/trivial-devices.txt

Please Cc as well the DT ml.

Regards,
Benoit
