David,
I'd met xrun on some embedded platform, which will only report hw_ptr
at period boundary. Maybe it shouldn't use tsched, I'm not sure. Sorry
for inconvenience.

Integrate UCM basic functions into alsa card module
Add use_ucm to udev detect module
Add UCM modifier functions into alsa card module

In UCM basic functions, we only assign intended roles from modifier
to sink/source, but we don't have a chance to set the ucm modifiers.
Here we amend the functions so that when special roled stream start
or stop or moved, we have the following results:
1. stream will be routed to sink/source
