[PATCH 1/2] interconnect: Add a common standard aggregate function

[PATCH 1/2] interconnect: Add a common standard aggregate function

[Georgi Djakov]

Currently there is one very standard aggregation method that is used by
several drivers. Let's add this as a common function, so that drivers
could just point to it, instead of copy/pasting code.

[PATCH 2/2] interconnect: qcom: Use the standard aggregate function

[Georgi Djakov]

Now we have a common function for standard aggregation, so let's use it,
instead of duplicating the code.
