disp: msm: remove use of drm_display_mode vrefresh

Use of drm_display_mode vrefresh is being deprecated in
upstream DRM framework. Downstream driver need to use
drm_mode_vrefresh API from now on.

This change removes dependency on drm_display_mode vrefresh
and replaces it with drm_mode_vrefresh API in SDE, DSI and
DP driver. In addition, it also modifies drm_display_mode clock
to align with upstream approach where an uncompressed mode clock
is required to match drm_mode_vrefresh API.
