A number of generally useful updates to the cursor code. The cursor code performs format conversion to the hardware's ARGB444 format and calculation of a checksum in a single function. Patch 1 splits this into two steps. Patch 2 then implements the format conversion with DRM's format helpers. Other drivers can now reuse the code. With the format handling separated, patch 3 adds support for ARGB4444, which is the hardware's native format. Patch 4 moves cursor handling into a separate source file. Tested on AST2600.
