PCI: imx6: Add external reference clock input mode support

Browse source

i.MX95 PCIes have two reference clock inputs: one from internal PLL, the
other from off chip crystal oscillator. The "extref" clock refers to a
reference clock from an external crystal oscillator.

Add external reference clock input mode support for i.MX95 PCIes.
