[PATCH v14 15/17] PCI: imx6: Disable clocks in reverse order of enable

[Richard Zhu <hongxing.zhu@xxxxxxx>]

From: Bjorn Helgaas <bhelgaas@xxxxxxxxxx>

imx6_pcie_clk_enable() enables clocks in the order:

  pcie_phy
  pcie_bus
  pcie
  imx6_pcie_enable_ref_clk

Change imx6_pcie_clk_disable() to disable them in the reverse order.
