i.MX PCIe controller is one dual mode PCIe controller, and can work either
as RC or EP.

This series add the i.MX PCIe EP mode support. And had been verified on
i.MX8MQ, i.MX8MM EVK and i.MX8MP EVK boards.

In the verification, one EVK board used as RC, the other one used as EP.
Use the cross TX/RX differential cable connect the two PCIe ports of these
two EVK boards.

NOTE:
Re-base to 6.1-rc1, and re-send the v4 series.
BTW, the following PHY changes [1] is required when apply this series.

[1] https://patchwork.kernel.org/project/linux-pci/cover/1665625622-20551-1-git-send-email-hongxing.zhu@nxp.com/

Main changes from v3 -> v4:
- Add the Rob's ACK in the dt-binding patch.
- Use "i.MX" to keep spell consistent.
- Squash generic endpoint infrastructure changes of
  "[12/14] PCI: imx6: Add iMX8MM PCIe EP mode" into Kconfig changes.

Main changes from v2 -> v3:
- Add the i.MX8MP PCIe EP support, and verified on i.MX8MP EVK board.
- Rebase to latest pci/next branch(tag: v6.0-rc1 plus some PCIe changes).

Main changes from v1 -> v2:
- Add Rob's ACK into first two commits.
- Rebase to the tag: pci-v5.20-changes of the pci/next branch.

Ping.
Almost one month pass away after this re-send of v4 series. 
Any comments?

Thanks.

Can you rebase on top of v6.2-rc1 and resend it please ? I will merge
the dt bindings and PCI changes then.

Thanks,
