serial: sh-sci: Add support SCIF of SH7723
SH7723 has two types of SCIF (SCIF and SCIFA). The current sh-sci driver supports only SCIFA, and calculation methods of SCBRR are different. This patch support this methods. Signed-off-by: Nobuhiro Iwamatsu <iwamatsu.nobuhiro@renesas.com> Signed-off-by: Paul Mundt <lethal@linux-sh.org>
