[PATCH] powerpc/p1022ds: fix audio-related properties in the device tree

[Timur Tabi]

On the Freescale P1022DS reference board, the SSI audio controller is
connected in "asynchronous" mode to the codec's clocks, so the device tree
needs an "fsl,ssi-asynchronous" property.

Also remove the clock-frequency property from the wm8776 node, because
the clock is enabled only if U-Boot enables it, and U-Boot will set the
property if the clock is enabled.  A future version of the P1022DS audio
driver will configure the clock itself, but for now, the driver should
not be told that the clock is running when it isn't.

Without this patch, audio is broken on the P1022DS.  I don't know why I missed
this on the initial version of the device tree.  I will also post this
patch for the -stable trees.
