A bunch of SKL watermark-related structures have the cursor plane as a
separate entry from the rest of the planes. Since a previous patch
updated I915_MAX_PLANES such that those plane arrays now have a slot for
the cursor, update the code to use the new slot in the existing plane
arrays and kill off the cursor-specific structures.
There shouldn't be any functional change here; this is just shuffling
around how the data is stored in some of the data structures. The whole
patch is generated with Coccinelle via the following semantic patch:

v2: Use a PLANE_CURSOR enum entry rather than making the code reference
I915_MAX_PLANES or I915_MAX_PLANES+1, which was confusing. (Ander)
