Update all Kconfig files and Makefiles to rely on the kernel overlay
feature. In particular, don't include any Kconfig files or Makefiles
from other overlays. -I directives in CFLAGS are not yet cleaned up.

This is a driver which creates a test sensor used for latency
measurements. It simulates a sensor triggering an event through the
nvs framework. The event is triggered by a write to its sysfs "on_ms"
file. When the event is triggered, it also toggles the GPIO specified
in its DT entry to turn on an LED. This can be used with a high speed
camera to capture the event start time when doing latency measurements.
