[PATCH 03/19] bh1770glc: lux0_glass_factor & lux0_comp_factor on sysfs

[Andi Shyti]

From: Onur Atilla <oati...@gmail.com>

Introduced lux0_glass_factor and lux0_comp_factor on sysfs

lux0_glass_factor and lux0_sensor_comp_factor are provided as
read-only files on the sysfs structure of the bh1770glc optical sensor.
