video: backlight: adp8860: Fix ambient light zone overwrite handling
Get/Set current Ambient Light Zone. Reading should return integer between 1..3
(1 = Daylight, 2 = office, 3 = dark). Writing a value between 1..3 forces
the Backlight controller to enter the corresponding Ambient Light Zone.
Writing 0 returns to normal operation.
Fix valid range and make sure we subtract 1, since the register
definition (CFGR:BLV) requires it.
