From: Nicholas Kazlauskas <nicholas.kazlaus...@amd.com>
[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.
