[pulseaudio-discuss] [PATCH v3 1/8] card: Add variables for splitting up a profile

It can be useful for routing modules to know a profile's input
and output parts, in order to e g change output profile
while keeping the input profile unchanged.

For now filling in these fields is optional and a routing module
must be able to handle NULL in these fields.
