PCI: imx6: Skip controller_id generation logic for i.MX7D

Browse Source 
[ Upstream commit f068ffdd034c93f0c768acdc87d4d2d7023c1379 ]

The i.MX7D only has one PCIe controller, so controller_id should always be
0. The previous code is incorrect although yielding the correct result.

Fix by removing "IMX7D" from the switch case branch.
