snd-firewire-lib: add amdtp_stream_wait_run() with 100 msec timeout

When handling receive stream, amdtp stream is under long wait for callbacking.
If any AMDTP packets are received or isochronous context is not set correctly,
the pointer of PCM DMA buffer is not elapsed. Then application keep to wait
updating the buffer pointer.

amdtp_stream_wait_run() brocks processing till the first callback has come or
timeout. Each driver use this function to abort pcm substream.

Currently the timeout is 100 (STREAM_TIMEOUT_MS in amdtp.c) but I need to
consider proper value.

And in fact this function is not needed for transmit context because transmit
context is generated in system side, not device side. Then there is no need
to wait. But considering to synchronized streams, this is needed for both of
receive and transmit streams. Implementations is not done yet.
