sh: 18-bit SYS panel fix for SuperH Mobile LCDC
Fix the SuperH Mobile LCDC driver to make use of the full 18-bit DRD field in the LDDRDR register. Without this patch only 16-bit register access is possible. Needed by 18-bit SYS panels such as the one used on kfr2r09. Signed-off-by: Magnus Damm <damm@igel.co.jp> Signed-off-by: Paul Mundt <lethal@linux-sh.org>
