net: Add support for Power over Ethernet (PoE)

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 two specific PoE
controller, the Microchip PD692x0 and the TI TPS23881.
