Sagar Dharia 4ec2ff4a32 slimbus: Support more than 1 clients to use a channel ...

There is a possibility that 2 or more clients can use the same
channel, one as producer and the other(s) as sink.
The slim_query_ch API gives the ability for a client to specify
channel number it needs to use.
Reference counting is used to make sure channel is not deallocated
until the last caller deallocates it.
Another counter (def) is used to keep track of channel definition and
removal. Channel definition is sent to hardware when the producer
and/or consumer(s) connects ports to the channel. Channel is only
removed when all clients indicate they want to remove channel.
