Kuninori Morimoto 766812e6d5 ASoC: sh: fsi: enable chip specific data transfer mode
SupherH FSI2 can use special data transfer,
but it depends on CPU-FSI2 connection style.

We can use 16bit data stream mode if it was valid connection,
and it is required for 16bit data DMA transfer / SPDIF sound output.
We can use 24bit data transfer if it was invalid connection.

We can select connection type if CPU is SH7372,
and it is always valid connection if latest SuperH.

This patch adds new bus_option and fsi_bus_setup()
for supporting these feature.

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.

Lars-Peter Clausen 85e7652d89 ASoC: Constify snd_soc_dai_ops structs
Commit 1ee46ebd("ASoC: Make the DAI ops constant in the DAI structure")
introduced the possibility to have constant DAI ops structures, yet this is
barley used in both existing drivers and also new drivers being submitted,
although none of them modifies its DAI ops structure. The later is not
surprising since existing drivers are often used as templates for new drivers.
So this patch just constifies all existing snd_soc_dai_ops structs to eliminate
the issue altogether.

The patch was generated with the following coccinelle semantic patch:
// <smpl>

identifier ops;

-struct snd_soc_dai_ops ops =
