The meaning of 'default' for the enable_guc module parameter has been
updated to accurately reflect what is supported on current platforms.
So start using the defaults instead of forcing everything off.
Although, note that right now, the default is for everything to be off
anyway. So this is not a change for current platforms.

What is the BKM to use this with multi-GPU setups? Specifically I have a
TGL+DG1 laptop (off the shelf) and want to have GuC with DG1 only. If I
pass i915.enable_guc=3 it seems it wants to enable it for TGL as well
and wedges the GPU if it can't?
