Subject: [PATCH] os: NextDPMSTimeout: mark intentional fallthroughs in switch

The comment at the top of the function tells humans the fallthroughs
are intentional, but gcc doesn't parse that.

Clears 3 -Wimplicit-fallthrough warnings from gcc 14.1

(cherry picked from commit b306df5a6060beea82b5157c3603593527b220b0)
