platform/x86: int3472: Stop using gpiod_toggle_active_low()
Use the new skl_int3472_gpiod_get_from_temp_lookup() helper to get a gpio to pass to register_gpio_clock(), skl_int3472_register_regulator() and skl_int3472_register_pled(). This removes all use of the deprecated gpiod_toggle_active_low() and acpi_get_and_request_gpiod() functions.
