kernel: 5.10: Backport pending pci-aardvark changes fixing MSI support
Backport Aardvark PCIe controller driver changes that fix MSI support,
that were recently sent to the linux-pci mailing list [1].
These changes fix MSI and MSI-X support for this PCIe controller, which,
among other things, make it possible to use NVMe drives with this PCIe
controllers.
