[PATCH v5 0/5] Add i.MX943 PCIe supports

[Richard Zhu]

This patch-set adds i.MX943 PCIe supports on EVK board. Please pay
attention to that it relies on the patch-set[1], and the PCIe1 port on
the EVK board relies on the [2].

Both of them are included in the v7.0 kernel.

Changes in v5:
- Add Reviewed-by tag in first patch.
- Add i.MX94/i.MX943 compatible strings.
- Add "dma" irq for i.MX94/i.MX943 PCIe.
- Add 'fsl,max-link-speed = <3>;' back. Because that Link speed is decided
by pcie_link_speed[pci->max_link_speed]; Found it when one Gen3 NVME SSD is
used in the tests.

Changes in v4:
- Add missing space after comma or '='.
- Remove 'fsl,max-link-speed = <3>;' in dts, since it's not required anymore.

Changes in v3:
- Fix build warning in the dtbs_check.

Changes in v2:
- Refine the nodes sequence refer to Frank's comments.
- Rely on [3], and remove the duplacated codes mentioned by Sherry.
