A bunch of changes to refine i.MX PCIe driver.
- Add ref clock gate for i.MX95 PCIe by #1, #2 and #9 patches.
  The changes of clock part is here [1].
  [1] https://patchwork.kernel.org/project/linux-arm-kernel/cover/1725525535-22924-1-git-send-email-hongxing.zhu@nxp.com/
- #3 and #4 patches clean i.MX PCIe driver by removing useless codes.
  Patch #3 depends on [2].

- Make core reset and enable_ref_clk symmetric for i.MX PCIe driver by
  #5 and #6 patches.
- Use dwc common suspend resume method, and enable i.MX8MQ, i.MX8Q and
  i.MX95 PCIe PM supports by #7 and #8 patches.

v3 changes:
- Update EP binding refer to comments provided by Krzysztof Kozlowski.
  Thanks.

v2 changes:
- Add the reasons why one more clock is added for i.MX95 PCIe in patch #1.
- Add the "Reviewed-by: Frank Li <Frank.Li@nxp.com>" into patch #2, #4, #5,
  #6, #8 and #9.
