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. root@linaro-alip:~# grep pcie /sys/kernel/debug/clk/clk_summary clk_pciephy_ref 1 1 24000000 0 0 clk_pcie_pm 0 0 24000000 0 0 clk_pcie_core_cru 0 0 125000000 0 0 clk_pciephy_ref100m 0 0 100000000 0 0 aclk_pcie 0 0 148500000 0 0 aclk_perf_pcie 0 0 148500000 0 0 pclk_pcie 0 0 37125000 0 0 clk_pcie_core 0 0 0 0 0 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.
