The imx6sl low power mode implementation inherits imx6q/dl one, and pm-imx6q.c can just work for imx6sl with some minor updates. Let's enable imx6sl suspend support by reusing pm-imx6q.c and use cpu_is_imxXX() to handle the those minor differences between imx6sl and imx6q/dl. Signed-off-by: Shawn Guo <shawn.guo@linaro.org>
