[PATCH v2 0/3] net: pse-pd: add poll path and LED trigger support

[Carlo Szelinsky <github@szelinsky.de>]

This series adds poll-based event detection and LED trigger support
to the PSE core subsystem.

Patches 1-2 introduce the poll path independently of LED support,
so it can be tested in isolation on boards with and without IRQ
configured.

Patch 3 adds LED triggers that hook into the shared event handling
path introduced by patch 2.

Changes since v1:
- Split single patch into 3 separate patches
- Extracted pse_handle_events() and devm_pse_poll_helper() as a
  standalone poll path (patches 1-2), testable without LED code
- Added DT binding for poll-interval-ms as a separate patch
- Renamed led-poll-interval-ms to poll-interval-ms for generic use
- Fire LED triggers from the notification path rather than a
  separate poll loop

Tested on Realtek RTL9303 with HS104 PoE chip, poll path only
(without IRQ configured). Verified PD connect/disconnect notifications
and LED trigger state changes. Testing with IRQ configured is still
needed to verify the refactored pse_isr() path.
