[ARM] Orion: rework MPP handling
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.
