Extend device tree bindings to support drive strength configuration for the
ksz* switches. Introduced properties:
- microchip,hi-drive-strength-microamp: Controls the drive strength for
high-speed interfaces like GMII/RGMII and more.
- microchip,lo-drive-strength-microamp: Governs the drive strength for
low-speed interfaces such as LEDs, PME_N, and others.
