In the case of MDIO bus registration failure due to no external PHY
devices is connected to the MAC, clk_disable_unprepare() is called in
stmmac_bus_clk_config() and intel_eth_pci_probe() respectively.
The second call in intel_eth_pci_probe() will caused the following:-

Yes, it's really an issue. My original thought is to combine common clocks and private clocks into stmmac_bus_clks_config() via plat_stmmacenet_data::clks_config callback,
let stmmac core to enable/disable all clocks.
Due to common and private clocks are enabled in specific platform driver, so let error handing for disabling these clocks from specific drivers is more reasonable.
