thanks for review.
Imho it should be separated...if someone thinks it needs to be changed later it will be changed not only for mt8195...a generic name can also cause problems if the next soc has different value.

Ok,i drop the comments (maybe except the wed one where the name in technical document (i used for constants) does not point to wed function.
