drm/amd/display: remove checking sink in is_timing_changed

Browse source

[Why]
Sometimes, such as sleep wake, the link->local sink pointer changed,
but the dc_stream_state->sink pointer is not changed. The checking
of timing_changed reports wrong result, lead to link tear down
unexpected wrongly.

[How]
SST compare local sink, MST compare proper remote link.
