From: Lad Prabhakar <prabhakar.mahadev-lad.rj@bp.renesas.com>
Unify the probe implementations of the VSC85xx PHY family into a single
vsc85xx_probe_common() helper. The existing probe functions for the
vsc85xx, vsc8514, vsc8574, and vsc8584 variants contained almost
identical initialization logic, differing only in configuration
parameters such as the number of LEDs, supported LED modes, hardware
statistics, and PTP support.
Introduce a vsc85xx_probe_config structure to describe the per-variant
parameters, and move all common setup code into the shared helper. Each
variant's probe function now defines a constant configuration instance
and calls vsc85xx_probe_common().
Also mark the default LED mode array parameter as const to match its
usage.

From: Lad Prabhakar <prabhakar.mahadev-lad.rj@bp.renesas.com>
Add support for the PHY LED controller in the MSCC VSC85xx driver. The
implementation provides LED brightness and hardware control through the
LED subsystem and integrates with the standard 'netdev' trigger.
Introduce new register definitions for the LED behavior register
(MSCC_PHY_LED_BEHAVIOR = 30) and the LED combine disable bits, which
control whether LEDs indicate link-only or combined link and activity
status. Implement a helper, vsc8541_led_combine_disable_set(), to update
these bits safely using phy_modify().
Add support for LED brightness control and hardware mode configuration.
The new callbacks implement the standard LED class operations, allowing
user control through sysfs. The brightness control maps to PHY LED force
on/off modes. The hardware control get and set functions translate
between the PHY-specific LED mode encodings and the LED subsystem
TRIGGER_NETDEV_* rules.
The combine feature is managed automatically based on the selected
rules. When both RX and TX activity are disabled, the combine feature is
turned off, causing LEDs to indicate link-only status. When either RX or
TX activity is enabled, the combine feature remains active and LEDs
indicate combined link and activity.
Register the LED callbacks for all VSC85xx PHY variants so that the LED
subsystem can manage their indicators consistently. Existing device tree
LED configuration and default behavior are preserved.

v2->v3:
- Added Reviewed-by tag.
v1->v2:
- Added LED control support to all VSC85xx PHY variants.
- Renamed led callbacks to vsc85xx_* for consistency.
- Defaulted the LEDs on probe to the default array before parsing DT.
- Used phy_modify() in vsc85xx_led_brightness_set()
- Return value of phy_read() checked in vsc85xx_led_hw_control_get()
- Reverse Christmas tree in vsc85xx_led_hw_is_supported()
- Updated the commit message to clarify the LED combine feature behavior.
