[PATCH v5 0/4] Spilt PCIe node to comply with hardware design

[Chuanjia Liu]

In current 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.

Split the PCIe node for MT2712 and MT7622 platform to fix MSI issue
and comply with the hardware design.

change note:
  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.
