[ALSA] hda_intel prefer 24bit instead of 20bit

Browse Source 
If I understand the hda_intel code, for format > 20bit it only advertise
the SNDRV_PCM_FMTBIT_S32_LE format and play it at 32 bit, 20 bit or 24 bit.
But if the 20bit and 24bit are available, actually it prefer the 20bit
format. This path is to prefer the 24bit format instead of 20bit.
