[ARM] EDMINIV2: add support for LED and power button
This patch provides standard GPIO LED control for the ED Mini V2, with software blinking only (CPLD hardware blinking capability is not used). This patch also provides status of the power button as a standard GPIO input event. Signed-off-by: Albert Aribaud <albert.aribaud@free.fr> Signed-off-by: Nicolas Pitre <nico@marvell.com>
