Subject: [PATCH 20/21] ASoC: codecs: Enable AB8500 CODEC for Device Tree

We have all of the AB8500 devices into the Device Tree to accurately
represent the hardware. We will also be passing configuration
information into the AB8500 Codec from Device Tree. The only reason
we're still registering them using the MFD API is to overcome addressing
issues encountered earlier. Each 'device' still belongs in the 'device'
tree.
If we were to take this Device Tree and use it on something non-Linux,
that OS will still need to know about each of the AB8500 devices and
every associated configuration option. Only in Linux do we continue to
register them though a different API, which doesn't affect any other OS.
