Merge branch 'extend-dt-bindings-for-pse-pd-controllers-and-update-prtt1c-dts'

Oleksij Rempel says:

====================
Extend dt-bindings for PSE-PD controllers and update prtt1c dts

This patch set comes in response to issues identified while adding PoDL
PSE support to the stm32 prtt1c device tree. The existing pse-pd device
tree bindings did not allow node name patterns like "ethernet-pse-0" and
"ethernet-pse-1", leading to validation failures.

To address these false positives in validation, the device tree bindings
are extended to support these node name patterns. Alongside this, an
example node is added to aid in the improved validation process.
