drm/gma500: Remove unnecessary include statements for drm_crtc_helper.h

Several source files include drm_crtc_helper.h without needing it or

compile-time dependencies.

Directly include required headers and drop drm_crtc_helper.h where
possible.

Neither the drm core nor any of the drivers really need the raw_edid field

creates confusion about who is responsible for freeing the memory it points
to and setting the field to NULL afterwards, leading to memory leaks and
dangling pointers.
