Subject: [PATCH v3 Resend 00/13] ASoC: dmaengine updates, secondary CPU DAI
 for Odroid

This is a rebased version with the build break fixed and added Krzysztof's 
Acks. My apologies, I double checked there is no build errors between patches 
this time.

Below is cover letter text from v2.

This series restores support for the secondary CPU DAI in samsung/i2s.c
driver and adds support for secondary CPU DAI on Odroid boards.

I have added 4 more clean up patches comparing to first version of the
patch set (16/22...19/22).

The first patch adds new platform device for the secondary PCM, I tried to
avoid registering new platform device in probe() as it doesn't play well
with deferred probing but couldn't find a way to avoid that new device,
unique devices are needed to register "PCM" components for each CPU DAI.

Patches 2/21...11/21 are mostly a clean up, following conversion to single
component with multiple DAIs, allowing to reference both primary/secondary
DAI in DT.

The patch set has been tested on Odroid U3, XU3, XU4 and Mini2440
(s3c2440 non-DT) boards.

Changes since v1 ((addressing Krzysztof's review comments):
 - added a comment, whitespace change in patch 1/21
 - dropped unnecessary new line addition from patch 1/21
