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.
