Expand the configuration of the hw_params to include the IEC-60958
channel status word and the CEA-861 audio infoframe. The configuration
of such structures depends on the snd_pcm_hw_params received. A
omap_dss_audio is used to pass the configuration parameters to DSS.

Instead of accessing the HDMI IP directly, the CPU DAI driver takes
advantage of the audio interface provided by the DSS device driver.
The ASoC driver will link the DSS audio functionality with ALSA by
calling the appropriate DSS device driver functions at the relevant
moments. For this, three new DAI operations are added: trigger, prepare
and shutdown operations.
At the moment, it is assumed that only one HDMI display is available
in the system, as it is the case in OMAP4. However, in the future,
one DAI for each HDMI display should be provided.

Create a struct hdmi_priv to store the relevant data of the CPU DAI
driver. As more data is added to the driver, having all the data
in the same location eases its handling. At the moment, only the DMA
configuration parameters are included in the structure.
Also, the required memory is allocated using devm_kzalloc rather than
using a static global variable.

In order to utilize the new OMAP HDMI codec and the updated name of
the device of the CPU DAI, update the names at the drivers accordingly.
While there, also update the name of the machine driver to be more
generic and encompass more OMAP processors featuring HDMI and not
only OMAP4.

In preparation to Device Tree support.
With DT booted kernel we can not rely on pdata which used to
hold information needed for the driver at runtime.
Use the card's driver data to hold these informations from now on.

There is no need to have two snd_soc_dai_link structure for the two setup
the machine driver supports.
We can just tell core to register only the first link if the DMIC link is
not in use on the device.

In capture stream the buffer size does not need to be constrained to be
bigger then the McBSP FIFO.
In capture the FIFO content is taken out in period length burst, this
enusres that the FIFO is not going to overflow.

Take the DMA packet mode into use when the McBSP is configured in element
dma_op_mode if the stream is not mono.
In this way we transfer one sample from/to McBSP FIFO upon DMA request.
This change only affects OMAP3+ versions, where the McBSP ports have FIFO.

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.

Introduce codec for HDMI. At the moment, this is a dummy codec. In the
future it will parse the EDID to modify the supported parameters, such
as the number of channels and the sample rates. At the moment, it blindly
supports all the sample rates and audio channels described in the HDMI
1.4a specification.
