CONFIG_PHY_FSL_IMX8M_PCIE has been set to 'y' now.
Good point -- cleaned up CONFIG_PCS_XPCS, too.
I've thought about it some more and think that maybe it's premature for LVDS;
I see hardware on the horizon, but the more I think about it, I'd rather have
hardware to test in hand before it gets enabled.
