AMDGPU: Assume xnack is enabled by default

This is the conservatively correct default. It is always safe to
assume xnack is enabled, but not the converse.

Introduce a feature to blacklist targets where xnack can never be
meaningfully enabled. I'm not sure the targets this is applied to is
100% correct.
