sh: kfr2r09 board support - SCIF console

Browse Source 
This patch adds basic kfr2r09 board support. Only
the SCIF1 console is supported with this patch, but
this patch and a proper sh7724 configuration is all
that is needed. Combine with an initramfs to have a
small RAM based kernel and distribution booted as
zImage from RAM via JTAG.
