Describe the bug

static rt_err_t drv_pwm_enable(struct gd32_pwm *pwm, const struct rt_pwm_configuration *configuration,
                               rt_bool_t enable)
{
    if(channel_num == 0)
    {
        LOG_E("GD32 PWM channel starts from 1!\n");
        return -RT_EINVAL;
    }

channel_num 未定义

Other additional context

另外可以考虑pwm的驱动将定时器和引脚配置相分离 用户自己去实现pwm的输出引脚配置 以获得对更多型号的支持

应该是这次改动带进来的 a10ac69
