[PATCH 6.0 0270/1073] drm/msm/dpu: use drm_dsc_config instead of msm_display_dsc_config

Greg Kroah-Hartman

From: Dmitry Baryshkov <dmitry.baryshkov@linaro.org>

[ Upstream commit 46dd0c0658ff5783acce37dcfe437e2a79a9934e ]

There is no need to use the struct msm_display_dsc_config wrapper inside
the dpu driver, use the struct drm_dsc_config directly to pass pps data.
