新开这个 PR 继续 #10536 ，用 dev-pwm 开发分支代替原 PR 中的 master 分支。 |

第四次 review。
还有一些小问题，请继续修改。

check_channel 的返回值类型和定义不匹配，请统一。这有好几处请一并修改。
| struct k230_pwm_dev *dev = &pwm_devs[i]; | ||
| dev->base = (rt_ubase_t)rt_ioremap((void *)(dev->base), sizeof(kd_pwm_t)); | ||
| dev->device.ops = &drv_ops; | ||
| ret = rt_device_pwm_register(&dev->device, dev->name, &drv_ops, (void *)dev->base); |

rt_device_pwm_register 的第三个参数确定需要传入吗？

rt_pwm_set/rt_pwm_enable/rt_pwm_disable 这些函数都有返回值的，需要 assert
|
好的，我改一下，感谢汪老师提醒 |
Added a PWM driver and a test file test_pwm.c. The test uses PWM to control the LED brightness, to check if the driver works correctly. Signed-off-by: XU HU <1337858472@qq.com>
