PCI: rockchip: Factor out rockchip_pcie_disable_clocks()

Factor out rockchip_pcie_disable_clocks() so it can be reused by other
functions.

No functional change intended, but it does change the order of unpreparing
clocks in the rockchip_pcie_resume_noirq() error path so it matches the
other paths.
