AOD: selectively register sensors that use prox

Allow some devices to only register sensors that use prox when
the display state is off or in doze on certain devices to
avoid white prox dot behind display.

The delay shouldn't be perceptible - when the device isn't in low-power
mode yet, we rely on regular touch from the display.
