It's feasible, however, I feel it doesn’t seem semantically appropriate.
Since, the etmv4_config is a configuration and TBH, it could be not
embedded in to etmv4_drvdata.

Though the usages where the chnaged fucntion, the config're all embeded.
However, If we introduce the etm4_get_drvdata_from_config(),
We need to check the drvdata pointer is valid since it passes the config
not embeded and this would be more strange.

So, I think it seems better to the caps arguments.
