iio: tsl2772: Add support for Avago APDS9900/9901 ALS/Proximity sensor

Browse Source 
The Avago APDS9900/9901 has a similar register layout to the
TAOS/AMS TSL2772 but features a unique set of configurations. Add support
for the APDS9900/9901 into the TSL2772 driver by adding the required
device-specific configurations.
