PCI: imx6: Move the imx6_pcie_ltssm_disable() earlier
Move the imx6_pcie_ltssm_disable() earlier and place it just behind the
imx6_pcie_ltssm_enable(), since it might not be only used by suspend
callback directly.
To be symmetric with imx6_pcie_ltssm_enable(), add the IMX6Q and IMX8MQ
switch cases in imx6_pcie_ltssm_disable().
