drm/amd/display: Fix Vega10 black screen after mode change
[Why]
The sequence is slightly changed when bring .set_bandwidth out
from the end of programming backend to the end of programming
surface. Vega10 doesn't like to get clocks updated if
stream_count is zero in the current context (Atomic Reset).
[How]
Do not update clocks if no stream is showing up in the context.
Fixes 1b2b130192 "dc: Remove 300Mhz minimum disp clk limit."
