The Ethernet LDO needs to be enabled to make the PHY GPIO reset taking effect, which uses the MDIO bus level reset. 2. The SoC GCC uniphy AHB and SYS clocks need to be enabled to make the ethernet PHY device accessible. 3. To provide the clock to the ethernet, the CMN clock needs to be initialized for selecting reference clock and enabling the output clock. 4. Support optional MDIO clock frequency config. 5. Update dt-bindings doc for the new added properties. Changes in v2: * remove the PHY related features such as PHY address program and clock initialization. * leverage the MDIO level GPIO reset for qca8084 PHY. Changes in v3: * fix the christmas-tree format issue. * improve the dt-binding changes. Changes in v4: * improve the CMN PLL reference clock config. * improve the dt-binding changes.
