ALSA: firewire-lib: rename parameter setting function for AM824 with FDF field
The value of FDF field in CIP header is protocol-dependent. Thus, it's better to allow data block processing layer to decide the value in any timing. In AM824 data format, the value of FDF field in CIP header indicates N-flag and Nominal Sampling Frequency Code (sfc). The N-flag is for switching 'Clock-based rate control mode' and 'Command-based rate control mode'. In our implementation, 'Clock-based rate control mode' is just supported. Therefore, When sampling transfer frequency is decided, then the FDF can be set. This commit replaces 'amdtp_stream_set_parameters' with 'amdtp_am824_set_parameters' to set the FDF. This is the same timing to decide the ration between the number of data blocks and the number of PCM frames.
