Sorry, but no. Please just duplicate whatever information you need from
these helpers into your driver. The decision was made recently to remove
these helpers because they were a premature generalization and unlikely
to be useful very widely. See this commit:

drm/tegra: Move drm_dp_link helpers to Tegra DRM
During the discussion of patches that enhance the drm_dp_link helpers it
was concluded that these helpers aren't very useful to begin with. After
all other drivers have been converted not to use these helpers anymore,
move these helpers into the last remaining user: Tegra DRM.
If at some point these helpers are deemed more widely useful, they can
be moved out into the DRM DP helpers again.

Your new driver here doesn't change that, in my opinion, so just follow
what we did for other drivers and duplicate the corresponding code into
the driver.
