Commit Message

The downstream kernel has infrastructure for passing votes from different
interconnect nodes onto different RPMh RSCs. This neither implemented, not
is going to be implemented upstream (in favor of a different solution
using ICC tags through the same node).

Unfortunately, as it happens, meaningless (in the upstream context) parts
of the vendor driver were copied, ending up causing havoc - since all
"per-RSC" (in quotes because they all point to the main APPS one) BCMs
defined within the driver overwrite the value in RPMh on every
aggregation.

To both avoid keeping bogus code around and possibly introducing
impossible-to-track-down bugs (busses shutting down for no reason), get
rid of the duplicated BCMs and their associated ICC nodes.

Thanks Konrad for catching this, I do see these nodes in other Qualcomm 
SoCs upstream (atleast sm8350/sm8450 and sm8550), perhaps they need to 
be cleaned up as well?
