spa: add profile param

Browse source 
Make a profile param that can be used to configure a node with a
certain profile.
Use the profile to configure the ports on splitter and merger and
get rid of the dynamic ports.
Use the profile to configure the client-node and audio-dsp.
Don't try to link more ports than available between client-node and
dsp.
