iio: Add tsl4531 ambient light sensor driver
driver for the TSL4531 family of 16-bit I2C ambient light
sensors; information is here:
http://www.ams.com/eng/Products/Light-Sensors/Ambient-Light-Sensor-ALS/TSL45315
the chip offers simple lux output
v3 (thanks Lars-Peter Clausen):
* add mutex to when updating integration time
* fix chip ID checking
* code cleanups
v2:
* rename to tsl4351
* use INT_TIME

This driver can also be built as a module. If so, the module
will be called tsl2563.

+ Say Y here if you want to build a driver for the TAOS TSL4531 family
+ of ambient light sensors with direct lux output.

+ To compile this driver as a module, choose M here: the
+ module will be called tsl4531.
