Dmitry Torokhov 1892e87a3e powerpc/warp: switch to using gpiod API
This switches PIKA Warp away from legacy gpio API and to newer gpiod
API, so that we can eventually deprecate the former.

Because LEDs are normally driven by leds-gpio driver, but the
platform code also wants to access the LEDs during thermal shutdown,
and gpiod API does not allow locating GPIO without requesting it,
the platform code is now responsible for locating GPIOs through device
tree and requesting them. It then constructs platform data for
leds-gpio platform device and registers it. This allows platform
code to retain access to LED GPIO descriptors and use them when needed.
