sh: Solution Engine 7722 board support.
This adds more full-featured support for the SH7722 Solution Engine. Previously this was using the generic board, and lacked most of the peripheral support. Signed-off-by: Ryusuke Sakato <sakato.ryusuke@renesas.com> Signed-off-by: Paul Mundt <lethal@linux-sh.org>
