This driver open-codes a few of the DPCD register reads when it can be
simplified by using the helpers instead. This series reworks the MSM DP
driver to use the DPCD helpers and removes some dead code along the way.
There's the potential for even more code reduction around the test
registers, but I haven't tried to do that yet.
For the whole series:

Using drm_dp_get_phy_test_pattern() / drm_dp_set_phy_test_pattern()
would be definitely a benefit, especially since the latter one has
support for DP >= 1.2, while msm DP code doesn't.
