drm/tilcdc: Disable sync lost interrupt if it fires on every frame

Disable the sync lost interrupt if it fires on every frame for 50
consecutive frames in a row. This is relatively sure sign of the sync
lost interrupt being stuck and firing on every frame even if the
display otherwise appears to work OK.
