ARM: ux500: delete custom pin control system
At the beginning of the first patch series I included the custom ux500 pin control system to make sure I could eventually replace it with the standard subsystem driver. So now that we've done so, let's remove it. Acked-by: Stephen Warren <swarren@wwwdotorg.org> Signed-off-by: Linus Walleij <linus.walleij@linaro.org>
