+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

+Upgrade the power and reset button handling for the NAS100D:
+ * Convert GPIO and IRQ handling to use the <asm/gpio.h> api.
+ * Perform the reset only after the power button has been held down
+   for at least two seconds.  Do 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 nas100d.h
+ * Add LED constants to nas100d.h while we're there.
+Also, update the board LED setup code to use constants.
