[Freedreno] [PATCH v4 5/6] drm/msm/dsi: update hdisplay calculation for dsi_timing_setup

[Jessica Zhang]

hdisplay for compressed images should be calculated as bytes_per_slice *
slice_count. Thus, use MSM DSC helper to calculate hdisplay for
dsi_timing_setup instead of directly using mode->hdisplay.

Changes in v3:
- Split from previous patch
- Initialized hdisplay as uncompressed pclk per line at the beginning of
  dsi_timing_setup as to not break dual DSI calculations

Changes in v4:
- Moved pclk_per_intf calculations to DSC hdisplay adjustments
