Subject: [PATCH v7 04/10] PCI: imx6: Correct controller_id generation logic for i.MX7D

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.

Fixes: 2d8ed461dbc9 ("PCI: imx6: Add support for i.MX8MQ")
