I believe this needs to be
if (IS_BXT_REVID(dev_priv, BXT_REVID_D0, BXT_REVID_FOREVER) ...
There were unavoidable flickering/underrun issues on the earlier
steppings due to memory fetch issues for the second color plane. Those
issues were only fixed on the E0 SoC stepping (which incorporates the D0
Display/GT).
Same change for your sprite plane changes in the next patch.
