PCI: rockchip: Clean up PHY if driver probe or resume fails
We observed that the clk_pciephy_ref is still enabled when we fail to probe
the driver.

clk_pciephy_ref is used by the PHY driver and we need to properly disable
it for this case. Add error handling in rockchip_pcie_init_port() and
rockchip_pcie_resume_noirq() to fix this issue.
