PCIe missing on RK3399

[Vicente Bergas]

Hi,
i've tested the Linux kernel 6.13-rc1 and rc2 and in both cases PCIe
is not detected on the RK3399 platform (rk3399-gru-kevin), whereas the
kernel version 6.12.3 works fine.

6.13 configuration is based on the same one as 6.12 and there aren't
any significant PCI-related differences.

The messages from dmesg on 6.13 don't show any PCI-related errors.

Does somebody know what is going on?

Regards,
  Vicente.
