Subject: net: pse-pd: Remove unused pse_ethtool_get_pw_limit function
 declaration

Removed the unused pse_ethtool_get_pw_limit() function declaration from
pse.h. This function was declared but never implemented or used,
making the declaration unnecessary.

Subject: net: pse-pd: Add power limit check

Checking only the current limit is not sufficient. According to the
standard, voltage can reach up to 57V and current up to 1.92A, which
exceeds the power limit described in the standard (99.9W). Add a power
limit check to prevent this.

Subject: net: pse-pd: Use power limit at driver side instead of current limit

The regulator framework uses current limits, but the PSE standard and
known PSE controllers rely on power limits. Instead of converting
current to power within each driver, perform the conversion in the PSE
core. This avoids redundancy in driver implementation and aligns better
with the standard, simplifying driver development.

Remove at the same time the _pse_ethtool_get_status() function which is
not needed anymore.

Subject: net: pse-pd: Split ethtool_get_status into multiple callbacks

The ethtool_get_status callback currently handles all status and PSE
information within a single function. This approach has two key
drawbacks:

1. If the core requires some information for purposes other than
   ethtool_get_status, redundant code will be needed to fetch the same
   data from the driver (like is_enabled).

2. Drivers currently have access to all information passed to ethtool.
   New variables will soon be added to ethtool status, such as PSE ID,
   power domain IDs, and budget evaluation strategies, which are meant
   to be managed solely by the core. Drivers should not have the ability
   to modify these variables.

To resolve these issues, ethtool_get_status has been split into multiple
callbacks, with each handling a specific piece of information required
by ethtool or the core.

From 4640a1f0d8f2246f34d6e74330d7e7d2cf75605b Mon Sep 17 00:00:00 2001
From: Kory Maincent <kory.maincent@bootlin.com>
Date: Fri, 10 Jan 2025 10:40:28 +0100
Subject: net: pse-pd: Remove is_enabled callback from drivers

The is_enabled callback is now redundant as the admin_state can be obtained
directly from the driver and provides the same information.

To simplify functionality, the core will handle this internally, making
the is_enabled callback unnecessary at the driver level. Remove the
callback from all drivers.
