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.

Some nodes are incorrectly marked as RPM-controlled (they have RPM
master and slave ids assigned), but are actually controlled by the
application CPU instead. The RPM complains when we send requests for
resources that it can't control. Let's fix this by replacing the IDs,
with the default "-1" in which case no requests are sent.

The buswidth of the pcnoc_s_* nodes is actually not 8, but
4 bytes. Let's fix it.

Add driver for the Qualcomm interconnect buses found in MSM8916 based
platforms. The topology consists of three NoCs that are controlled by
a remote processor that collects the aggregated bandwidth for each
master-slave pairs.
