drm/amd/display: Fix incorrect DSC instance for MST
[Why] DSC debugfs, such as dp_dsc_clock_en_read,
use aconnector->dc_link to find pipe_ctx for display.
Displays connected to MST hub share the same dc_link.
DSC instance is from pipe_ctx. This causes incorrect
DSC instance for display connected to MST hub.
[How] Add aconnector->sink check to find pipe_ctx.
