Hi,
While working on the t5325 audio support, I found two small buglets in the
kirkwood ASoC support.
The first one is aiming at fixing mono audio playback and should fix mono
playback for all platforms.
The second is adding support for muting/unmuting kirkwood audio. It's
mainly usefull for the t5325 which has a bootloader playing with this
(hardware default is not muted).

Kirkwood controller needs to be informed if the audio stream is mono
or not. Failing to do so will result in playing at the wrong speed.

The controller has mute/unmute capability and some bootloader may mute
them at boot. If it's not handled, all things will seem to be working
but no sound will come out of the speaker/headphone.
