Currently in the case where some of the allocations fail for dce110_tgv, dce110_xfmv, dce110_miv or dce110_oppv then the exit return path ends up leaking allocated objects.

2017-11-28drm/amd/display: Add timing validation against dongle capEric Yang4-3/+91
For DP active dongles, the dpcd dongle caps are read but not used to validate mode timing. This addresses this. In particular, this change fixes light up on the HDMI 4k TV connected through DP active dongle. Since the 4k TV defaults to YCbCr420, which the dongle don't support. This change does not address MST cases, a more generalized approach must be taken for that.
