This patch series aims at adding support for PoE (Power over Ethernet),
based on the already existing support for PoDL (Power over Data Line)
implementation. In addition, it adds support for one specific PoE
controller, the Microchip PD692x0.

The PD692x0 driver is based on the patch merged in an immutable branch
from Jakub repo. It is Tagged at:
git://git.kernel.org/pub/scm/linux/kernel/git/kuba/linux.git firmware_loader-add-upload-error
The patch is already merged in net-next.

In detail:
- Patch 1 to 6 prepare net to support PoE devices.
- Patch 7 and 8 add PD692x0 PoE PSE controller driver and its binding.

Changes in v2:
- Extract "firmware_loader: Expand Firmware upload error codes patches" to
  send it alone and get it merge in an immutable branch.
- Add "c33" prefix for PoE variables and enums.
- Enhance few comments.
- Add PSE Documentation.
- Make several changes in pd692x0 driver, mainly for readibility.
- Link to v1: https://lore.kernel.org/r/20231116-feature_poe-v1-0-be48044bf249@bootlin.com
