pinctrl: pinconf: Add generic helper function for freeing mappings
The pinconf-generic.h file exposes functions for creating generic mappings but it does not expose a function for freeing the mappings. Add a function for freeing generic mappings. Signed-off-by: Jon Hunter <jonathanh@nvidia.com> Signed-off-by: Linus Walleij <linus.walleij@linaro.org>
