net: phy: microchip_t1s: Add support for LAN867x Rev.D0 PHY

This patch series adds support for the latest Microchip LAN8670/1/2 Rev.D0
10BASE-T1S PHYs to the microchip_t1s driver.

The new Rev.D0 silicon introduces updated initialization requirements and
link status handling behavior compared to earlier revisions (Rev.C2 and
below). These updates are necessary for full compliance with the OPEN
Alliance 10BASE-T1S specification and are documented in Microchip
Application Note AN1699 Revision G (DS60001699G – October 2025).

Summary of changes:
- Implements Rev.D0-specific configuration sequence as described in AN1699
  Rev.G.
- Introduces link status control configuration for LAN867x Rev.D0.
