sh: kfr2r09 board support - SCIF console
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.
