  Log Message:
  -----------
  AMDGPU: Fix incorrectly selecting fp8/bf8 conversion intrinsics (#107291)

Trying to codegen these on targets without the instructions should
fail to select. Not sure if all the predicates are correct. We had
a fake one disconnected to a feature which was always true.

Fixes: SWDEV-482274
