Some of the newly added code is hidden inside of #ifdef
blocks, but one variable is unused when debugfs is disabled:
drivers/gpu/drm/amd/amdgpu/../display/amdgpu_dm/amdgpu_dm.c:8370:8: error: unused variable 'configure_crc' [-Werror,-Wunused-variable]
Change the #ifdef to an if(IS_ENABLED()) check to fix the warning
and avoid adding more #ifdefs.
Fixes: c920888c604d ("drm/amd/display: Expose new CRC window property")

After all users of the 'dm' warnings got hidden in an #ifdef,
the compiler started warning about it being unused:
drivers/gpu/drm/amd/amdgpu/../display/amdgpu_dm/amdgpu_dm.c:5380:33: error: unused variable 'dm' [-Werror,-Wunused-variable]
Add another such #ifdef.
Fixes: 98ab5f3513f9 ("drm/amd/display: Fix deadlock during gpu reset v3")
