[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.

ARM: orion5x: Fix GPIO enable bits for MPP9 Commit 554cdaefd1cf7bb54b209c4e68c7cec87ce442a9 ('ARM: orion5x: Refactor mpp code to use common orion platform mpp.') seems to have accidentally inverted the GPIO valid bits for MPP9 (only). For the mv2120 platform which uses MPP9 as a GPIO LED device, this results in the error: [ 12.711476] leds-gpio: probe of leds-gpio failed with error -22 Reported-by: Henry von Tresckow <hvontres@gmail.com> References: http://bugs.debian.org/667446 Signed-off-by: Ben Hutchings <ben@decadent.org.uk> Cc: stable@vger.kernel.org [v3.0+] Tested-by: Hans Henry von Tresckow <hvontres@gmail.com> Signed-off-by: Jason Cooper <jason@lakedaemon.net>
