Subject: drm/amd/display: Include missing header

The file amdgpu_dm_plane.c missed the header amdgpu_dm_plane.h, which
resulted on the following warning:

drivers/gpu/drm/amd/amdgpu/../display/amdgpu_dm/amdgpu_dm_plane.c:1046:5:

Therefore, include the missing header on the file and turn global functions
that are not used outside of the file into static functions.
