[PORT FROM R2] atomisp: remove unused types from atomisp.h

BZ: 17272

This patch removes types from atomisp.h that are not used in atomisp.h itself.
The use of the atomisp_frame structure is replaced by v4l2_framebuffer which was
introduced in v4l2 for exactly this use case. Also, since this is a v4l2 driver,
we should use v4l2 constructs for frames, not introduce our own.

This makes the atomisp interface smaller and easier to document.
