drm/i915/icl: Fix MG_DP_MODE() register programmingdrm-intel-next-fixes-2019-04-25
Fix the order of lane, port parameters passed to the register macro.
Note that this was already partly fixed by commit
37fc7845df7b6 ("drm/i915: Call MG_DP_MODE() macro with the right parameters order")
While at it simplify things by using the macro directly instead of an
unnecessary redirection via an array.
v2:
- Add a note the commit message about simplifying things. (José)
Fixes: 58106b7d816e1 ("drm/i915: Make MG PHY macros semantically consistent")
