Subject: [PATCH] PCI: controller: dwc: Make PCI_IMX6 depend on PCIEPORTBUS

Building a kernel with CONFIG_PCI_IMX6=y, but CONFIG_PCIEPORTBUS=n
produces a system where built-in PCIE bridge (16c3:abcd) isn't bound
to pcieport driver. This, in turn, results in a PCIE bus that is
capable of enumerating attached PCIE device, but lacks functional
interrupt support.

Assuming this is a reasonable dependency, shold this be done to more
than just i.MX6 driver?
