drm: Unexport drm_plane_helper_check_update

Browse Source 
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
