I think it's cleanest to calculate frame size conditionally based on
SND_SOC_DAIFMT_CBS_CFS or testing !in_freq and let the frame
size to be wlen * channels in other cases.

If it's based on !in_freq, then the in_freq must be set in
omap_mcbsp_dai_set_dai_sysclk only for OMAP_MCBSP_SYSCLK_xxx cases
since this function is called also when setting CLKR and FSR sources
(no need to pass frequency).
