Take into account the initial bandwidth from the framework and update
the internal sum and max values before committing if needed. This will
ensure that the floor bandwidth values are enforced until the providers
get into sync state.

Implement a function to parse the arguments of the "interconnects" DT
property and populate the interconnect path tags if this information
is available.

Currently, bcm-voter always assumes requests are made in KBps and that
BCM HW always wants them in Bps, so it always scales the requests by
1000. However, certain use cases and BCMs may use different units.
Thus, add support for BCM-specific scaling factors.

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