drm/i915: fix not reading DSC disable fuse in GLK
We were using GRAPHICS_VER() to handle SKL_DFSM register, which means we were not handling GLK correctly since that has GRAPHICS_VER == 9, but DISPLAY_VER == 10. Switch the entire branch to check DISPLAY_VER which makes it more in line with Bspec. Even though the Bspec has an exception for RKL in TGL_DFSM_PIPE_D_DISABLE, we don't have to do anything as the bit has disable semantic and RKL doesn't have pipe D. Bspec: 50075, 7548 Fixes: 2b5a4562edd0 ("drm/i915/display: Simplify GLK display version tests") Cc: Matt Roper <matthew.d.roper@intel.com> Signed-off-by: Lucas De Marchi <lucas.demarchi@intel.com> Reviewed-by: Matt Roper <matthew.d.roper@intel.com> Link: https://patchwork.freedesktop.org/patch/msgid/20210723234352.214459-1-lucas.demarchi@intel.com
