ASoC: SOF: imx: Add devicetree support to select topologies

We describe tplg_file_name and drv_name using snd_sof_of_mach
array and select correct machine description based on dts compatible
string.

ASoC: SOF: imx: Add SNDRV_PCM_INFO_BATCH flag

The sof imx pcm device is a device which should support
double buffering.

Found this issue with pipewire. When there is no
SNDRV_PCM_INFO_BATCH flag in driver, the pipewire will
set headroom to be zero, and because sof pcm device
don't support residue report, when the latency setting
is small, the "delay" always larger than "target" in
alsa-pcm.c, that reading next period data is not
scheduled on time.

With SNDRV_PCM_INFO_BATCH flag in driver, the pipewire
will select a smaller period size for device, then
the task of reading next period data will be scheduled
on time.

ASoC: SOF: make .remove callback return void

We don't use the returned value and return 0 anyways, let's follow the
example of platform drivers and simplify the definitions.

ASoC: SOF: Convert to platform remove callback returning void

The .remove() callback for a platform driver returns an int which makes
many driver authors wrongly assume it's possible to do error handling by
returning an error code. However the value returned is ignored (apart
from emitting a warning) and this typically results in resource leaks.

To improve here there is a quest to make the remove callback return
void. In the first step of this quest all drivers are converted to
.remove_new(), which already returns void. Eventually after all drivers
are converted, .remove_new() will be renamed to .remove().

The SOF platform drivers all use either sof_of_remove() or
sof_acpi_remove() which both return zero unconditionally. Change these
functions to return void and the drivers to use .remove_new(). There is
no semantical change.
