Ah, here's the likely reason for not sharing these, ast/cirrus have their
special dirtying stuff for fbdev emulation. And because the fbdev mmap
must have a stable pointer it can't use the ttm bo mmap magic of
automatically picking the right place for the mmap.
I'd say just leave these 2 drivers out as special cases.
