correctly do suspend/resume.

When using the legacy filter function channel requests we currently pass
the audio specific struct snd_dmaengine_dai_dma_data which isn't likely to
be helpful for actual filtering. Since there's already a field in the
structure called filter_data clearly intended for use here convert the
driver to use that.

All existing users of plain filter functions have been converted to use
an explicit compat function to override this behaviour except i.MX which
is working around this issue in its filter function and is updated to
just use filter_data directly here.

Some devices have more than just simple TX and RX DMA channels, for example
modern Samsung I2S IPs support a secondary transmit DMA stream which is
mixed into the primary stream during playback. Allow such devices to
specify the names of the channels to be requested in their dma_data.

Device tree support for Davinci Machine driver

When the board boots with device tree, the driver will receive card,
codec, dai interface details (like the card name, DAPM routing map,
phandle for the audio components described in the dts file, codec mclk
speed). The card will be set up based on this information. Since the
routing is provided via DT we can mark the card fully routed so core
can take care of disconnecting the unused pins.

AM33xx uses same McASP IP as the Davinci Platform. This patch updates
Kconfig and makefile to enable build for McASP, PCM & Codec drivers.

Setting a field in a static struct to NULL has no effect so don't bother
(and don't generate false positives for grep).

Currently the ep93xx DMA code is one of the few users relying on the fact
that the compat code uses the dma_data as the filter data for non-DT
channel requests. Since the rest of the core expects this to be a struct
snd_dmaengine_dai_data this isn't terribly helpful this will be changed to
use the already existing filter data so avoid breaking ep93xx by open
coding the current behaviour.
