ASoC: rsnd: remove default division of clock out

Current adg has default division for BRRA/BRRB, but it was created at
very beginning of the driver implementation, and is now an unnecessary
settings.

Because it has this default division, unexpected clockout might
be selected. For example if it requests only 44.1kHz base clockout,
unrequested 48kHz base clockout also will be selected.

This patch remove default division of clock out
