Kazuhiro Fujita c7dd89cafd serial: sh-sci: Make sure status register SCxSR is read in correct sequence 
commit 3dc4db3662 upstream.

For SCIF and HSCIF interfaces the SCxSR register holds the status of
data that is to be read next from SCxRDR register, But where as for
SCIFA and SCIFB interfaces SCxSR register holds status of data that is
previously read from SCxRDR register.

This patch makes sure the status register is read depending on the port
types so that errors are caught accordingly.
