log: add gpio number/value and execution result to log

Change to:
static void _control_led(peripheral_gpio_h gpio, int power_on)
{
    int ret;

    ret = peripheral_gpio_write(gpio, power_on);

    dlog_print(DLOG_INFO, LOG_TAG, "Write [0x%x] into GPIO%d, ret=%d.",
                power_on, GPIO_NUM, ret);
}
