I have two wireless cards connected to my i.MX6. One via USB and one via
PCIe. Both work just fine, but the way they are enumerated at bootup seems
completely random. They always get wlan0 or wlan1, but its never
consistent which one gets which.
I've tried adding some udev rules that specify the name based on the MAC
address, but they didn't seem to work.
How do I go about ensuring that the PCI device always gets wlan0 and the
USB device always gets wlan1?

You should look at the persistent rules which Debian and other generic
distributions use. Basically those rules rename the device after those
are discovered by the kernel and udev receives the event.
