[PATCH v9 0/3] Add i.MX943 PCIe supports

[Richard Zhu <hongxing.zhu@nxp.com>]

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 v9:
- Since the dt-binding changes have been merged, only the DTS changes are
being resent after rebasing to v7.1-rc1.

Note: The corresponding changes will be updated later after the following
two patch sets are merged, as suggested by Mani:
  - [PATCH V14 00/12] pci-imx6: Add support for parsing the reset property in new Root Port binding
  - [PATCH V2 0/8] PCI: imx6: Integrate pwrctrl API and update device trees

Changes in v8:
- Drop the redundant strings since they are compatible with i.MX95.

Changes in v7:
- Fix the checkpatch.pl warning in the first patch. Sorry for not
understanding the comments provided by Krzysztof in the v4 patch-set.
- Adjust the compatible strings in alphabetical order.

Changes in v6:
- Let i.MX94 and i.MX943 EP mode compatible strings fallback to i.MX95 EP
mode complatible string too.
- Add missing space after "=" in pcie0_ep node.

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.
