Introduce new DAI driver used for NXP's PDM MICFIL IP.
This block implements required digital interface to provide
a 24-bits audio signal from a PDM microphone bitstream in a configurable
output sampling rate.

The property descriptions contain a lot of unneeded and driver-
specific information. As such, make them shorter while removing
driver-specific information.

Add a DTS binding for the MediaTek Audio Front End device, and
definitions for the in-tree devices.
These .dts files were auto-generated from pre-existing SOF code (that
defined the devices as C structs) using a tool currently being
submitted in the SOF tree, thus are included here as separate files.
The expectation is that future variants will be authored in this
format directly. Longer term we can move them directly into the core
board DTS.

Add support for performing pinctrl operations. For now,
the only supported operation is applying the pinctrl default
state. Pinctrl is left optional to allow for scenarios in which
this is not required (e.g: AMP system in which another
OS configures the pinctrl).

Some SAI instances are mutliline, meaning they can have multiple
TX/RX data lines (channels). Depending on the board, the index
of the TX/RX data lines that are connected to the consumer
(e.g: the codec) may not always be 0. This commit fixes this
issue by adding support for passing the index of the used
TX/RX data lines through the DTS.

In preparation for supporting all synchronization modes, this
commit introduces the rx_sync_mode/tx_sync_mode DTS properties.
Using these, the user will be able to specify which synchronization
mode the SAI should use.
At the moment, the driver does nothing with the values from
said properties but still checks if their values are sane
(i.e: it checks if the directions are both in SYNC mode which
is forbidden). By default, if "rx_sync_mode" or "tx_sync_mode"
is not specified, the direction will be set to ASYNC mode.
As such, below one may find a couple of valid examples
depicting this idea:
tx_sync_mode = <0>;
rx_sync_mode = <0>;
is the same as not specifying any of the properties,
tx_sync_mode = <1>;
rx_sync_mode = <0>;
is the same as:
tx_sync_mode = <1>;

In ACE 2.0 platform (LNL) dmic got two new shim register ranges.
DMIC driver need to program them to configure the interface.
This patch adds new shims to device tree.

Add a fifo address as int value into dmic yaml to separate different
outputs (corresponds to different dais) from the same hw block. Also
change shim address from array to int value.

Fat finger mis-typed when I renamed the file last time.
So correctly name the file this time. Hopefully this is
correct and won't need anymore renaming... :(

() Fix the compatible string from "intel,dai,dmic" to
"intel,dai-dmic".
() Also rename the yaml file to have vendor name first.

All in tree device drivers use some form of DEVICE_DT_GET
so we no longer need to require label properties.
