Use Proximity Photodiodes for ALS Measurement. Connects the IR-sensitive
proximity photodiodes to the ALS engine in order to collect ALS data in the IR
band. The data registers contain the following channel data depending on the
LTF_USEPROX setting.

Sleep After Interrupt. Powers down the device at the end of a proximity/ALS
cycle if an interrupt has been generated. Note that SAI does not modify any
register bits directly, it rather uses the interrupt signal to turn off the oscillator. The
only way to "wake up" the device from SAI-sleep is by clearing the SAI_ACTIVE
flag.
