From: Kory Maincent (Dent Project) <kory.maincent@bootlin.com> Expand PSE callbacks to support the newly introduced pi_get/set_current_limit() and pi_get_voltage() functions. These callbacks allow for power limit configuration in the TPS23881 controller. Additionally, the patch includes the detected class, the current power delivered and the power limit ranges in the status returned, providing more comprehensive PoE status reporting.

This is a common pattern in this driver, we read and write two registers in one run and then calculate bit offset for the channel, can you please move it in to separate function. This can be done in a separate patch if you like.
