pinctrl: get_group_pins() const fixes
get_group_pins() "returns" a pointer to an array of const objects, through a pointer parameter. Fix the prototype so what's pointed at by the returned pointer is const, rather than the function parameter being const. This also allows the removal of a cast in each of the two current pinmux drivers. Signed-off-by: Stephen Warren <swarren@nvidia.com> Signed-off-by: Linus Walleij <linus.walleij@linaro.org>
