From: Fenglin Wu <fenglinw@xxxxxxxxxxxxxx> The initial value of is_enabled flag is read out from hardware in pmic_gpio_populate(), and it will be set in pmic_gpio_config_set() if pinconf is defined. For any GPIOs disabled initially in hardware which only have pinmux defined, they won't be enabled in pmic_gpio_set_mux() calling. So set is_enabled flag in set_mux() to ensure the GPIO module could be enabled in above case.
