Subject: iio: ltr501: ltr559: fix initialization of LTR501_ALS_CONTR

The ltr559 chip uses only the lowest bit of the ALS_CONTR register to configure between active and stand-by mode. In the original driver BIT(1) is used, which does a software reset instead.

This patch fixes the problem by using BIT(0) as als_mode_active for the ltr559 chip.
