drm/i915/icl: Fix MG_DP_MODE() register programming 

Fix the order of lane, port parameters passed to the register macro.

Note that this was already partly fixed by commit
37fc7845df ("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)
