Sophgo's SG2044 SoC uses Synopsys Designware PCIe core
to implement RC mode.
For legacy interrupt, the PCIe controller on SG2044 implement
its own legacy interrupt controller. For MSI/MSI-X, it use an
external interrupt controller to handle.
The external MSI interrupt controller patch can be found on [1].
As SG2044 needs a mirror change to support the way to send MSI
message and different irq number.
