sh: LED9, LED10 and LED11 support for Solution Engine 7724
This patch adds support for LED9, LED10 and LED11 on the Solution Engine 7724 board. If CONFIG_PM is enabled then these LEDs are used to show the hardware sleep mode used by the processor. Useful to debug cpuidle. Signed-off-by: Magnus Damm <damm@igel.co.jp> Signed-off-by: Paul Mundt <lethal@linux-sh.org>
