Lowering the bandwidth on the bus might have negative consequences if
it's done before all consumers had a chance to cast their vote. Now by
default the framework sets the bandwidth to maximum during boot. We need
to use the icc_sync_state callback to notify the framework when all
consumers are probed and there is no need to keep the bandwidth set to
maximum anymore.

There is a new helper function for removing all nodes. Let's use it instead
of duplicating the code.

The macro to generate a Bus Controller Manager (BCM) TCS command is used
by the interconnect driver but might also be interesting to other
drivers that need to construct TCS commands for sub processors so move
it out of the sdm845 specific file and into the header.

Add support for wake and sleep commands by using a tag to indicate
whether or not the aggregate and set requests fall into execution
state specific bucket.

Consumers may have use cases with different bandwidth requirements based
on the system or driver state. The consumer driver can append a specific
tag to the path and pass this information to the interconnect platform
driver to do the aggregation based on this state.
Introduce icc_set_tag() function that will allow the consumers to append
an optional tag to each path. The aggregation of these tagged paths is
platform specific.
