Currently, the DesignWare PCIe driver cannot configure interrupts on
SoC that do not support MSIX. All MSI interrupts are handled by CPU0.
Backport MSI affinity support for the PCI dwc driver from linux-next,
so now we can adjust MSI interrupts to other CPU cores.
Tested on HINLINK H28K (RK3528) and OrangePi R2S (Ky X1).
