Upgrade the power and reset button handling for the NAS100D:
From 6261e59795d861f21f63878944900a3da713348c Mon Sep 17 00:00:00 2001
From: Rod Whitby <rod@whitby.id.au>

Subject: ixp4xx: Button and LED updates for the nas100d board (Patch #4768)
* 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.
solder 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.
* Update the board LED setup code to use those constants.
