drm/amd/display: Use is_dig_enable function instead of dcn10 hardcode

Browse Source 
[Why]
This can differ depending on ASIC and we can end up skipping all
transmitter control if we're relying on the wrong bit as a shortcut
for whether link is on/off.

[How]
The ASIC table itself provides the correct DIG check, use that instead
of the dcn10 hardcode.
