So after some more testing on different hardware I stumbled upon the problem that USB autosuspend doesn't work properly anymore.
I have an onboard LTE module that is connected to OTG2 on the i.MX8MM. When using the mainline TF-A (that enables USB power-domains by default) and removing the power-domain control from the kernel, the device comes up after a few seconds and is enumerated on the bus.
Now, when I let the kernel control the power-domains, the device comes up at boot, but isn't enumerated on the USB bus. As soon as I disable autosuspend for the port, it comes up.
Is this something that needs to be fixed on the USB driver side or is something to be considered for the GPCv2 driver?
