"almost 4.9" does not help, sorry.

dw-hdmi is well supported on i.MX6 with mainline, so you could simply try that.
Try booting 5.1.11 on your custom board with a very minimal dts with HDMI support.
Then you can test suspend/resume and see if HDMI hangs or not.

I am not able to reproduce this hang. As I mentioned yesterday suspend/resume is working just fine.
We would be glad to help fixing the hang if you could reproduce it with a mainline kernel.
