Refactor the routines for "calculating" the size of the WARP microcode. The
two routines (one for G200 and one for G400) were replaced with static const variables and a single function that returns the correct size. The code to generate an error if the allocated WARP region is too small was refactored from mga_warp_install_{g200,g400}_microcode to mga_wrap_install_microcode. mga_warp_microcode_size is global to the MGA DRM because it will soon be used by code in another file.
