Update logic for sharing buffers and components

[ranj063]

If a comp is not shared, it is not necessary to invalidate/writeback at all.

what about connected pipelines? A typical example is a "host pipeline" connected to a "DAI pipeline" over a mixer. Additionally, there can be a further "host pipeline," connected to the same mixer. Would we catch all cases when one of those pipelines contains a component, run on a different core?

Ack, so it sounds like we need a utility function like

int comp_is_shared()
{
   /* comp is shared if source or sink component/pipeline is on a different core */
}

Can one of the admins verify this patch?
