ALSA: fireworks: configure sampling transfer frequency in pcm.hw_params callback
This commit is a part of preparation to perform allocation/release
of isochronous resources in pcm.hw_params/hw_free callbacks.
At present, several operations are done in pcm.prepare callback. To
reduce load of the callback, This commit splits out an operation to
set sampling transfer frequency in pcm.hw_params callback.
