pinctrl: conjure names for unnamed pins
If pins with blank names are registered, we assign them names on-the-fly on the form "PINn" where n is the pin number for that pin on the specific controller. Acked-by: Stephen Warren <swarren@nvidia.com> Signed-off-by: Linus Walleij <linus.walleij@linaro.org>
