[media] v4l2-framework: replace g_chip_ident by g_std in the examples

The framework documentation used the g_chip_ident op as an example. This
op has been removed, so replace its use in the examples by the g_std op.

 You can call an ops function either directly:
 
-	err = sd->ops->core->g_chip_ident(sd, &chip);
+	err = sd->ops->core->g_std(sd, &norm);
 
 but it is better and easier to use this macro:
 
-	err = v4l2_subdev_call(sd, core, g_chip_ident, &chip);
+	err = v4l2_subdev_call(sd, core, g_std, &norm);
 
 The macro will to the right NULL pointer checks and returns -ENODEV if subdev
-is NULL, -ENOIOCTLCMD if either subdev->core or subdev->core->g_chip_ident is
-NULL, or the actual result of the subdev->ops->core->g_chip_ident ops.
+is NULL, -ENOIOCTLCMD if either subdev->core or subdev->core->g_std is
+NULL, or the actual result of the subdev->ops->core->g_std ops.
 
 It is also possible to call all or a subset of the sub-devices:
 
-	v4l2_device_call_all(v4l2_dev, 0, core, g_chip_ident, &chip);
+	v4l2_device_call_all(v4l2_dev, 0, core, g_std, &norm);
 
 Any subdev that does not support this ops is skipped and error results are
 ignored. If you want to check for errors use this:
 
-	err = v4l2_device_call_until_err(v4l2_dev, 0, core, g_chip_ident, &chip);
+	err = v4l2_device_call_until_err(v4l2_dev, 0, core, g_std, &norm);
 
 Any error except -ENOIOCTLCMD will exit the loop with that error. If no
 errors (except -ENOIOCTLCMD) occurred, then 0 is returned.

 任何不支持此操作的子设备都会被跳过，并忽略错误返回值。但如果你需要

+	err = v4l2_device_call_until_err(v4l2_dev, 0, core, g_std, &norm);
 
 除 -ENOIOCTLCMD 外的任何错误都会跳出循环并返回错误值。如果（除 -ENOIOCTLCMD
 外）没有错误发生，则返回 0。
