sh775x: add new target to support SH7751R-based (SH4) boards

If SH4 hardware is not available for testing, the generated kernel and
rootfs can happily start up in qemu:

qemu-system-sh4 -M r2d -nographic -no-reboot -kernel openwrt-sh775x-zImage \
-append "console=ttySC1 noiotrap root=/dev/hda" -monitor null -serial null \
-serial stdio -drive file=openwrt-sh775x-rootfs-ext4.img,format=raw
