Clarification / more information: The missing RX 560 happens for a few boots
*after* the full system hang.  I.e. first I run Steam with DRI_PRIME=1, click
around for a bit until the system hangs (sometimes waiting alone seems to be
enough, though), then I hard-reset the system, when Linux started the RX 560 is
missing, I reboot, RX 560 is still missing, ... (loop for a few iterations)
..., RX 560 is back and we have a "regular boot".

One more bit of information (though probably still unrelated): The resolution
is correct when I do not plug in the RX 560, or connect the display to the RX
560 directly (and setup the mainboard firmware to use the dGPU as primary video
adapter).
