drm/msm/dp: check if VSC SDP is supported in DP programming
In the DP driver, check if VSC SDP is supported and propagate this value
to dp_panel. In dp_display's dp_mode, the out_fmt_is_yuv_420 parameter
must also utilize this value since YUV420 is only allowed when VSC SDP
is supported.
Changes in v2:
- Move DP programming when VSC SDP is supported to this patch
