This patch set is to support bucket in icc-rpm driver, so it implements
the similar mechanism in the icc-rpmh driver.
It uses interconnect path tag to indicate the bandwidth voting is for
which buckets, and there have three kinds of buckets: AWC, WAKE and
SLEEP, finally the wake and sleep bucket values are used to set the
corresponding clock (active and sleep clocks). So far, we keep the AWC
bucket but doesn't really use it.

It adds interconnect driver support for QCM2290 platform. The topology
consists of 3 NoCs: BIMC, Config NoC (CNOC) and System NoC (SNOC). SNOC
is a QCOM_ICC_QNOC type device, as well as its 3 virtual child devices,
QUP, MMNRT and MMRT. QUP is owned by RPM and thus has no .regmap_cfg,
while the other 2 share the same .regmap_cfg with SNOC (parent).

Add driver for the Qualcomm interconnect buses found in SM8350 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.

Introduce a driver for the Qualcomm interconnect busses found in
the SDM630/SDM636/SDM660 SoCs.
The topology consists of several NoCs that are controlled by a
remote processor that collects the aggregated bandwidth for each
master-slave pairs.
On a note, these chips are managing the "bus QoS" in a "hybrid"
fashion: some of the paths in the topology are managed through
(and by, of course) the RPM uC, while some others are "AP Owned",
meaning that the AP shall do direct writes to the appropriate
QoS registers for the specific paths and ports, instead of sending
an indication to the RPM and leaving the job to that one.

Add RPM based interconnect driver implements the set and aggregate
functionalities that translates bandwidth requests into RPM messages.
These modules provide a common set of functionalities for all
Qualcomm RPM based interconnect providers and should help reduce code
duplication when adding new providers.

On some Qualcomm SoCs, there is a remote processor, which controls some of
the Network-On-Chip interconnect resources. Other CPUs express their needs
by communicating with this processor. Add a driver to handle communication
with this remote processor.
