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
