The board is using McASP2 for both analog (tlv320aic3106) and
HDMI (SiI9022) audio.
12.288MHz oscillator provides the MCLK for both aic3106 and SiI9022.

Hi,

Changes since v1:
- Rename the sii9022_mclk ficed clock to aud_mclk (as it is named in the schema)
  and use it within the sound card dai nodes for the codecs.

Regards,
Peter
