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].

- #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.
