ALSA: lola - Add Lola-specific module options
Added granularity and sample_rate_min module options. The former controls the h/w access granularity. As default, it's set to the max value 32. The latter controls the minimum sample rate in Hz, as default 16000. Signed-off-by: Takashi Iwai <tiwai@suse.de>
