ALSA: oxygen: simplify model-specific MCLK handling
Replace the get_i2s_mclk callback with tables of MCLK values. This simplifies the MCLK-handling code in both the framework and the model- specific drivers. Signed-off-by: Clemens Ladisch <clemens@ladisch.de> Signed-off-by: Takashi Iwai <tiwai@suse.de>
