According to the documentation gpio_free should only be called from task
context only. To make this more explicit add a might sleep to all
implementations.
This patch changes the gpio_free implementations for the arm architecture.
DaVinci is skipped on purpose to simplify the merge process for patches
switching it over to use gpiolib as per request by David Brownell.

Instead of having board code poke directly into the MPP configuration
registers, and separately calling orion5x_gpio_set_valid_pins() to
indicate which MPP pins can be used as GPIO pins, introduce a helper
function for configuring the roles of each of the MPP pins, and have
that helper function handle gpio validity internally.
