The MEI VSC driver currently oopses and may crash the system on suspend.
The other drivers required to use MEI VSC driver's services are not in
upstream yet, disable the MEI VSC driver by marking it BROKEN until it is
fixed.

Hi Greg,
It'd be nice to have this in 6.8 or if that fails, merge it in early
stable releases. This issue causes crashes on Tiger lake, Alderlake and
others on system suspend.
As the driver isn't used for anything (in upstream) quite yet, the patch
marks it BROKEN for now.

Please ignore this patch. This one should be merged instead:
