you can have as many dwc3 instances as you want. AM437x has two dwc3
instances, so do several other TI and Qcom devices, albeit not on
PCIe. Some recent Intel platforms have more than dwc3 in the die over
(fake?) PCIe.
In any case, there are no limitations (apart from memory and available
PCIe ports) to having more than one dwc3 over PCIe. If you can find a
discrete device like that, it's difficult to say.
