At the moment HAS_GUC_UCODE == HAS_GUC == IS_GEN9 ==
(INTEL_INFO(dev)->gen_mask & BIT(8)), which is true but not one. And
module parameters are integers and not booleans so compiler will not
normalize the value for us.
Quick and easy fix for the GuC loading code and the whole area can
be evaluated afterwards.

Or we could just fix the IS_GENx() macros:

drm/i915: Explicitly convert some macros to boolean values
:D
Still, I think being explicit when assigning boolean type macros to
integer is a good thing to do. Because I thought true is defined as
non-zero in C. Unless I am behind the times.
