drm: Unexport drm_plane_helper_check_update

It's for legacy drivers only (atomic ones should use
drm_atomic_helper_check_plane_state() instead), and there's no users
left except the one in the primary plane helpers.

-/**
- * drm_plane_helper_check_update() - Check plane update for validity
- * @plane: plane object to update
- * @crtc: owning CRTC of owning plane
- * @fb: framebuffer to flip onto plane
- * @src: source coordinates in 16.16 fixed point
- * @dst: integer destination coordinates
- * @rotation: plane rotation
- * @min_scale: minimum @src:@dest scaling factor in 16.16 fixed point
- * @max_scale: maximum @src:@dest scaling factor in 16.16 fixed point
- * @can_position: is it legal to position the plane such that it
- *                doesn't cover the entire crtc?  This will generally
- *                only be false for primary planes.
- * @can_update_disabled: can the plane be updated while the crtc
- *                       is disabled?
- * @visible: output parameter indicating whether plane is still visible after
- *           clipping
- *
- * Checks that a desired plane update is valid.  Drivers that provide
- * their own plane handling rather than helper-provided implementations may
- * still wish to call this function to avoid duplication of error checking
- * code.
- *
- * RETURNS:
- * Zero if update appears valid, error code on failure
