Since iMX6Q/DL PCIe has the PM limitation (ERR005723 "PCIe PCIe does
not support L2 Power Down").
System suspend/resume would be broken by PCIe, if PCIe is enabled.
Only enable PCIe in the xxx-pcie.dts files to avoid the brokens when
other xxx.dtb files are used on sabresd and sabreauto boards.

We have several imx6 dts files that currently enable pcie.
Can't we have a proper software workaround for this issue instead?

Hi Fabio:
Up to now, unfortunately, there is no solid confidential SW workaround for this issue.

No. There are hundreds of boards based on i.MX6Q/DL. We are not going
to maintain a -pcie.dts for every single one of them.
