ASoC: meson: axg-toddr: fix channel order on g12 platforms
On g12 and following platforms, The first channel of record with more than
2 channels ends being placed randomly on an even channel of the output.

On these SoCs, a bit was added to force the first channel to be placed at
the beginning of the output. Apparently the behavior if the bit is not set
is not easily predictable. According to the documentation, this bit is not
present on the axg series.

Set the bit on g12 and fix the problem.

ASoC: meson: axg-fifo: fix fifo threshold setup
On TODDR sm1, the fifo threshold register field is slightly different
compared to the other SoCs. This leads to the fifo A being flushed to
memory every 8kB. If the period is smaller than that, several periods
are pushed to memory and notified at once. This is not ideal.

Fix the register field update. With this, the fifos are flushed every
128B. We could still do better, like adapt the threshold depending on
the period size, but at least it consistent across the different
SoC/fifos

ASoC: meson: Drop superfluous ioctl PCM ops
ASoC PCM core deals the empty ioctl field now as default.
Let's kill the redundant lines.

ASoC: meson: axg-toddr: expose all 8 inputs
The TODDR component, as it, has a maximum of 8 input. Depending on
the SoC, these may not all be connected or some input components may
not be supported

Instead of decribing only the connected inputs, describe them all
and let ASoC routing do the rest.

ASoC: meson: axg-toddr: add g12a support
Since the g12a SoC fifo can set the fifo initial start address, we must
make sure to actually reset the write pointer to this address when
starting a capture.

ASoC: meson: axg-toddr: add support for spdifin backend
add IEC958_SUBFRAME_LE to the list of format accepted by the fifo frontend.

As opposed to what was initially noted in the toddr dai driver, the spdifin
does not place the msb at bit 28, it just output a whole spdif subframe.

Placing the msb at bit 28 in the toddr driver just filters out the parity,
user, channel status and validity bits. It is better to just provide the
whole spdif subframe to the userspace and let the iec958 plugin deal with
it.
