+Upgrade the power and reset button handling for the DSMG600:
+ * Remove the superfluous declaration of ctrl_alt_del().
+ * Convert GPIO and IRQ handling to use the <asm/gpio.h> api.
+ * Perform the reset on the release of the power button, so that
+ NAS devices which have been set to auto-power-on (by bridging
+ the power button) do not continuously power cycle.
+ * Remove all superflous constants from dsmg600.h
