I want to also include kerneldoc from the header (for static inline
functions and structs), but fishing the righ pieces out of a giant
header is a real pain. So split things out.
Note that it's not a really clean header with sane include orders, but
given's drm historical knack for giant headers detangling this is a
major task.
v2: Also extract struct drm_cmdline_mode.
