The new sound card DT binding is used for Odroid XU3 in order
to properly support the HDMI audio path.  Clocks configuration is
changed so the I2S controller is now the bit clock and the frame clock
master.  The EPLL output clock is now the audio root clock adjusted to
each audio sample rate.

to avoid it on Odroid XU4, which has no audio codec.

The Odroid XU4 board does not have audio codec so before adding DTS
for new board split the audio codec to separate DTSI file. Include
the audio codec DTSI in Odroid XU3 and XU3-Lite boards.
