From: Sergei Shtylyov <sergei.shtylyov@cogentembedded.com>

Describe  the external audio clocks (signals AUDIO_CLK[ABC]) required by
the sound driver.  Boards that provide audio clocks need to  override the
clock frequencies.

This patch is based on the commit 0d3dbde84a45 ("ARM: shmobile: r8a7791:
add  audio clock on DTSI").
