Arrange PSE core and update TPS23881 driver

This patch includes several improvements to the PSE core for better
implementation and maintainability:

- Move the conversion between current limit and power limit from the driver
  to the PSE core.
- Update power and current limit checks.
- Split the ethtool_get_status callback into multiple callbacks.
- Fix PSE PI of_node detection.
- Clean ethtool header of PSE structures.

Additionally, the TPS23881 driver has been updated to support power
limit and measurement features, aligning with the new PSE core
functionalities.
