Even if modecookie is used as opaque type from wscons related
routines, "struct video_modetiming" is better than "void *",
because compiler can check its type with the former.

Only "struct video_modetiming;" (rather than "#include <dev/ic/vidmode.h>")
is needed in wscons related source files for the opaque case.

P.S.
I think it is better to use this opaque technique for other opaque
types (e.g. cookie for interrupt handler), too.
