drm/amd/display: avoid disable otg when dig was disabled

Browse source

[Why]
This is a workaround for an dcn3.1 hang that happens if otg dispclk
is ramped while otg is on and stream enc is off.
But this w/a should not trigger when we have a dig active.

[How]
Avoid disable otg when dig was disabled.
