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 are here [1].

- #3 and #4 patches clean i.MX PCIe driver by removing useless codes.
Patch #3 depends on dts changes. And the dts changes had been applied
by Shawn, there is no dependecy now.
- 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.
v4 changes:
It's my fault that I missing Manivanna in the reviewer list.
I'm sorry about that.
- Rebase to v6.12-rc3, and resolve the dtsi conflictions.
Add Manivanna into reviewer list.
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.
