[LAD] Jack not starting MOD-Duos Audio Interface Driver

[Rafael Guayer]

I solved this by adding the format S24_3LE to:

aSoC Codec Driver snd_soc_dai_driver->formats
aSoC Plataform Driver (DMA) snd_pcm_hardware->formats
aSoC Plataform Driver (I2S) snd_soc_dai_driver->capture->formats and
snd_soc_dai_driver->playback->formats

The codec CS4245 only works with 32 bit word size, so i am converting from
S24_3LE in the I2S plataform driver by setting the word size 32bits.

Thanks!
