R-Car sound has clock pin for each SSI, and sometimes,
these pins are shared with paired SSI.
It may sometimes become "SSI-A clock pin is master" and
"SSI-B clock pin is slave", but "SSI-A/B clock pins are shared".
SSI-B needs SSI-A clock in this case.
Current R-Car sound driver is using RSND_SSI_xxx flag
to control this kind of shared pin behavior.
But, this information, especially clock master setting,
can be got from ASoC set_fmt settings.
This patch removes rsnd_ssi_mode_init() and extend rsnd_ssi_mode_set()
to controlling pin settings via .set_fmt.
This patch doesn't removes RSND_SSI_CLK_FROM_ADG flag at this point
to avoid conflict branch merging between ASoC <-> SH-ARM.

ASoC: More updates for v3.11
Some more fixes and enhancements, and also a bunch of refectoring for
AC'97 support which enables more than one AC'97 controller driver to be
built in.
Currently we can only have a single platform built in with AC'97 support
due to the use of a global variable to provide the bus operations. Fix
this by making that variable a pointer and having the bus drivers set the
operations prior to registering.
This is not a particularly good or nice approach but it avoids blocking
multiplatform and a real fix involves fixing the fairly deep problems
with AC'97 support - we should be converting it to a real bus.

fsi_hw_startup/shutdown() needs the setup of bus width,
but it is impossible to get parameter of snd_pcm_runtime at this timing.
So, these functions are changed so that be called from fsi_dai_trigger().

Leading up to the ->device_prep_slave_sg change in
185ecb5f4f 'dmaengine: add context
parameter to prep_slave_sg and prep_dma_cyclic' a generic wrapper was
added in place to guard against the API change, though the fsi driver
wasn't updated in the process (presumably its dmaengine support hadn't
been merged yet at the time). This trivially switches over to the new
wrapper and gets it building again.

Pull slave-dmaengine update from Vinod Koul:
"This includes the cookie cleanup by Russell, the addition of context
parameter for dmaengine APIs, more arm dmaengine driver cleanup by
moving code to dmaengine, this time for imx by Javier and pl330 by
Boojin along with the usual driver fixes."
Fix up some fairly trivial conflicts with various other cleanups.

This patch supports DMAEngine to FSI driver.
It supports only Tx case at this point.
If platform/cpu doesn't support DMAEngine, FSI driver will
use PIO transfer.
