PCI: imx6: Fix reference clock source selection for i.MX95
In the PCIe PHY init for the i.MX95, the reference clock source selection
uses a conditional instead of always passing the mask. This currently
breaks functionality if the internal refclk is used.
To fix this issue, always pass IMX95_PCIE_REF_USE_PAD as the mask and clear
bit if external refclk is not used. This essentially swaps the parameters.
