interconnect: qcom: x1e80100: Remove inexistent ACV_PERF BCM

Booting the kernel on X1E results in a message like:

[ 2.561524] qnoc-x1e80100 interconnect-0: ACV_PERF could not find RPMh address

And indeed, taking a look at cmd-db, no such BCM exists. Remove it.

interconnect: qcom: x1e80100: Remove bogus per-RSC BCMs and nodes

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.

interconnect: qcom: x1e80100: Add missing ACV enable_mask

The ACV BCM is voted using bitmasks. Add the proper mask for this
target.

interconnect: qcom: Add X1E80100 interconnect provider driver

Add driver for the Qualcomm interconnect buses found in X1E80100 based
platforms. The topology consists of several NoCs that are controlled by
a remote processor that collects the aggregated bandwidth for each
master-slave pairs.
