MLK-10747-1 video: ipu: Build ldb_di clock relevant code only for MX6 and MX53
The LDB is found in MX6 variants and MX53, so this patch makes the ldb_di clock relevant code be built only for them. Signed-off-by: Liu Ying <Ying.Liu@freescale.com> (cherry picked from commit c0dc175a9780505ec8939bda5dda9c2ec549a7f0)
