The PI of_node was not assigned in the regulator_config structure, leading
to failures in resolving the correct supply when different power supplies
are assigned to multiple PIs of a PSE controller. This fix ensures that the
of_node is properly set in the regulator_config, allowing accurate supply
resolution for each PI.

Expand PSE callbacks to support the newly introduced
pi_get/set_pw_limit() and pi_get_voltage() functions. These callbacks
allow for power limit configuration in the TPS23881 controller.
Additionally, the patch includes the pi_get_pw_class() the
pi_get_actual_pw(), and the pi_get_pw_limit_ranges') callbacks providing
more comprehensive PoE status reporting.

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.

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.

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.

When setting the PWOFF register, the controller resets multiple
configuration registers. This patch ensures these registers are
reconfigured as needed following a disable operation.

This driver frequently follows a pattern where two registers are read or
written in a single operation, followed by calculating the bit offset for
a specific channel.
Introduce helpers to streamline this process and reduce code redundancy,
making the codebase cleaner and more maintainable.

Cleaned up several functions in tps23881 by removing redundant checks on
return values at the end of functions. These check has been removed, and
the return statement now directly returns the function result, reducing
the code's complexity and making it more concise.

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.

Setting the max_uA constraint in the regulator API imposes a current
limit during the regulator registration process. This behavior conflicts
with preserving the maximum PI power budget configuration across reboots.
Instead, compare the desired current limit to MAX_PI_CURRENT in the
pse_pi_set_current_limit() function to ensure proper handling of the
power budget.

When stopping AP, mac80211 frees beacon template before it calls
driver's stop_ap operation. In other words, on the path of stopping
AP, ieee80211_beacon_get_template() must returns NULL in
mt7996_mcu_add_beacon(). In such case mt7996 immediately returns
-EINVAL without telling FW to disable the beacon.
This commit refactors mt7996_mcu_add_beacon() so that FW can be
correctly informed when disabling AP interface.

This commit includes two changes. First, enable "EHT MU PPDU With 4x
EHT-LTF And 0.8us GI" in EHT Phy capabilities element since hardware
can support. Second, fix the value of "Maximum number of supported
EHT LTFs" in the same element, where the previous setting of 3 in
Bit 3-4 was incorrect.

When the system suspend or resume, the WiFi driver sends
an hif_ctrl command to the firmware and waits for an event.
Due to changes in the event format reported by the chip, the
current mt7925's driver does not account for these changes,
resulting in command timeout. Add flow to handle hif_ctrl
event to avoid command timeout. We also exented API
mt76_connac_mcu_set_hif_suspend for connac3 this time.

When enter suspend/resume while in a connected state, the upper layer
will trigger disconnection before entering suspend, and at the same time,
it will trigger regd_notifier() and update CLC, causing the CLC event to
not be received due to suspend, resulting in a command timeout.
Therefore, the update of CLC is postponed until resume, to ensure data
consistency and avoid the occurrence of command timeout.

Use generic mt76 chanctx functions and look up phy from vif link.
The driver now uses only a single phy to handle multiple interfaces on
different channels. This is preparation for full MLO support.
