Hence that, the PCIe devices will not work properly if the irq number which required is more than 32. Split the PCIe node for MT2712 and MT7622 platform to fix MSI issue and comply with the hardware design. change note: v7:dt-bindings file was modified as suggested by Rob, other file no change. v6:Fix yaml error. make sure driver compatible with old and new DTS format. v5:rebase for 5.9-rc1, no code change. v4:change commit message due to bayes statistical bogofilter considers this series patch SPAM. v3:rebase for 5.8-rc1. Only collect ack of Ryder, No code change. v2:change the allocation of MT2712 PCIe MMIO space due to the allocation size is not right in v1.
