These pinconf/pinctrl definitions will be used by the next patches. The definitions was taken from public headers of linux-7.0. It's used by several linux pinctrl drivers, so it might be helpful for U-Boot as well. Pinconf definitions are placed near the corresponding U-Boot definitions in file include/dm/pinctrl.h. Pin/group/function definitions stored within the same path as in linux (include/linux/pinctrl/pinctrl.h).
