[U-Boot] [PATCH v2 0/3] dm: gpio: Add driver for MPC85xx GPIO controller

The functions for accessing GPIOs on MPC85xx are hardcoded in
arch/powerpc/include/asm/mpc85xx_gpio.h This leads to problems if another GPIO
controller supporting the driver model is to be used simultaneously.

Therefore, this patch moves the "static" functions into a DM-compatible driver,
and also introduces a set of functions into the GPIO uclass that expose the
controller's capability to switch individual GPIOs into open-drain-mode.
