powerpc/5200: Add Lite5200 on-board LEDs as devices
The Lite5200 evaluation board has a number of debug LEDs that Linux doesn't know about yet. This change adds a gpio-leds stanza to the lite5200 device tree so that the correct driver can get hooked up. Also, make use of the dtc labels feature to reduce the number of source lines required to add the gpio-controller property to the general purpose timer nodes. In addition, the required #gpio-cells properties are added to the common mpc5200b dtsi include file so that each board doesn't need to add them explicitly. This still doesn't enable gpio mode, 'gpio-controller' is required for that, but it means less work needs to be done by board ports.
