There are two independent PCIe controllers in MT2712 and MT7622 platform.
Each of them should contain an independent MSI domain.

In old dts architecture, MSI domain will be inherited from the root
bridge, and all of the devices will share the same MSI domain.Hence that,
the PCIe devices will not work properly if the irq number which required
is more than 32.
