Chiawen Huang 8353d30e74 drm/amd/display: disable stream if pixel clock changed with link active
[Why]
Vbios uses preferred timing to turn on edp but OS could use other
timing.  If change pixel clock when link active, there is unexpected
garbage on monitor.

[How]
Once pixel clock changed, the driver needs to disable stream.
