Remove legacy ambient light sensor logic
Remove legacy ambient light sensor logic

In maemo/meego times mce controlled ambient light sensor directly via
kernel interfaces and sensorfw asked mce to start/stop sensor via dbus
interface. The legacy logic for direct sensor control has already been
removed earlier, but the unneeded dbus methods for starting/stopping
the sensor are still littering mce code base.

Drop support starting/stopping ambient light sensor via dbus method calls.

[mce] Remove legacy ambient light sensor logic. Contributes to JB#27286
