Marek Vasut f7f9abc5ea phy: freescale: imx8m-pcie: Handle IMX8_PCIE_REFCLK_PAD_UNUSED 
The 'fsl,refclk-pad-mode' DT property used to select clock source for
PCIe PHY can have either of three values, IMX8_PCIE_REFCLK_PAD_INPUT,
IMX8_PCIE_REFCLK_PAD_OUTPUT, IMX8_PCIE_REFCLK_PAD_UNUSED. The first
two options are handled correctly by the driver, the last one is not,
this patch implements support for the last option.

The IMX8_PCIE_REFCLK_PAD_INPUT means PCIE_RESREF is PHY clock input,
the IMX8_PCIE_REFCLK_PAD_OUTPUT means PHY clock are sourced from SoC
internal PLL and output to PCIE_RESREF external IO pin. The last
IMX8_PCIE_REFCLK_PAD_UNUSED is a combination of previous two, PHY
clock are sourced from SoC internal PLL and not output anywhere.
