Several DRM core and helper source files include drm_crtc_helper.h
without needing it or only to get its transitive include statements;
leading to unnecessary compile-time dependencies.

Directly include required headers and drop drm_crtc_helper.h where
possible. The header file, drm_fixed.h, includes <linux/kernel.h>
for lower_32_bits().

drm_crtc_helper.c may not require drm/drm_crtc_helper.h, but it should
include it so we get a warning in case there is a mismatch between the
header file and the implementation.
I think sparse would also complain that the function is not declared
or something like that.

With this fixed:
