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.

"This is just *wrong*. You cannot hardcode the MMIO address in the driver.
Even though this code is old, you should fix it instead of building on top
of it.

IMX7D here is wrong athough check IMX8MQ_PCIE2_BASE_ADDR is not good
method. Previously try to use 'linux,pci-domain' to replace this check
logic. Need more discussion to improve it and keep old compatiblity.
Let's fix this code error firstly.
