[PATCH 5/7] drm/msm/dpu: rework vsync_source handling

[Dmitry Baryshkov]

The struct msm_display_info has is_te_using_watchdog_timer field which
is neither used anywhere nor is flexible enough to specify different
sources. Replace it with the field specifying the vsync source using
enum dpu_vsync_source.
