nocturne: Enable debouncing of SX9310 CLOSE / FAR IRQs

This is meant to solve an issue where the proximity sensor may fluctuate
between CLOSE / FAR in rapid succession upon the user removing their hand
from the unit, before settling on the correct output.

Using the hardware debouncing filter solves this issue and removes the
spurious fluctuations.

BRANCH=None
BUG=None
TEST=manual on Nocturne, observing events come in
