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. - microchip,io-drive-strength-microamp: Controls the drive strength for for undocumented Pads on KSZ88xx variants.
