The IMX7s does not have a PCI-e controller.  The IMX7d does have one,
but not the "s".

Enabling the controller driver on an IMX SoC that doesn't have it is
not exactly the end of the world and having to keep adding new IMX SOCs
to the list here is annoying.  So IMHO, it's ok to make this change
even if the controller is allowed on a superset of the SoCs that have
it.
