iio: ltr501: ltr559: fix initialization of LTR501_ALS_CONTR
commit 421a26f3d7a7c3ca43f3a9dc0f3cb0f562d5bd95 upstream.
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.
