pinctrl: nomadik: decomission non-DT boot path
After the patches deleting the last board registering this pin controller as a platform device has been deleted, proceed to remove the non-DT boot patch and depend on OF being available and the device to be coming up by a DT node. Signed-off-by: Linus Walleij <linus.walleij@linaro.org>
