Subject: [PATCH v2 8/8] drm/msm/dpu: drop now-unused condition for
 has_legacy_ctls

Now as we have dropped the DPU_CTL_SPLIT_DISPLAY from DPU >= 5.0
configuration, drop the rm->has_legacy_ctl condition which short-cutted
the check for those platforms.

Suggested-by: Marijn Suijten <marijn.suijten@...ainline.org>
Signed-off-by: Dmitry Baryshkov <dmitry.baryshkov@...aro.org>

Note, it is imposible to reoder commits in any other sensible way. The
DPU_CTL_SPLIT_DISPLAY can not be dropped before the patch that enables
single-CTL support.
