sh-sci: Extend sh-sci driver with early console V2
This is V2 of early serial console support for the sh-sci driver. The early serial console is using early platform devices and "earlyprintk". To use this feature the early platform devices must be broken out to one device per port and the desired port should be selected on the kernel command line like: "earlyprintk=sh-sci.N[,baudrate][,keep]" Signed-off-by: Magnus Damm <damm@opensource.se> Signed-off-by: Paul Mundt <lethal@linux-sh.org>
