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.

Add driver for interconnect busses found in MSM8909 based platforms.
The topology consists of three NoCs that are partially controlled by
a RPM processor.

In the downstream/vendor kernel from Qualcomm there is an additional
"mm-snoc". However, it actually ends up using the same RPM "snoc_clk"
as the normal "snoc". It looks like this is actually the same NoC
in hardware and the "mm-snoc" was only defined to assign a different
"qcom,util-fact" to increase bandwidth requests by a static margin.
In mainline we can represent this by assigning the equivalent "ab_coeff"
to all the nodes that are part of "mm-snoc" downstream.

Pull more bcachefs updates from Kent Overstreet:
 "Some fixes, Some refactoring, some minor features:

   - Assorted prep work for disk space accounting rewrite

   - BTREE_TRIGGER_ATOMIC: after combining our trigger callbacks, this
     makes our trigger context more explicit

   - A few fixes to avoid excessive transaction restarts on
     multithreaded workloads: fstests (in addition to ktest tests) are
     now checking slowpath counters, and that's shaking out a few bugs

   - Assorted tracepoint improvements

   - Starting to break up bcachefs_format.h and move on disk types so
     they're with the code they belong to; this will make room to start
     documenting the on disk format better.
