powerpc/4xx: Have Warp take advantage of GPIO LEDs default-state = keep
The GPIO LEDS driver now has a default state of "keep". Update the Warp DTS and platform file to take advantage of this new state. This removes the hardcoding of the two LEDs on the Warp. Signed-off-by: Sean MacLennan <smaclennan@pikatech.com> Signed-off-by: Josh Boyer <jwboyer@linux.vnet.ibm.com>
