Refactor device tree and driver to use separate named GPIO properties (dip-clk-gpios, dip-output-gpios, dip-load-gpios) for the SN74LV165A shift register instead of a single 'gpios' array. Update driver to match new bindings and simplify GPIO handling. Also improve sysfs attribute implementation and error handling. Signed-off-by: Oleg Karfich <oleg.karfich@wago.com>
