On most hardware platforms, SoundWire interfaces are pin-muxed with
other interfaces (typically DMIC or I2S) and the status of each link
needs to be checked at boot time.
For Intel platforms, the BIOS provides a menu to enable/disable the
links separately, and the information is provided to the OS with an
Intel-specific _DSD property. The same capability will be added to
revisions of the MIPI DisCo specification.

- Documentation updates for code-blocks
- Improvement from Pierre on intel and cadence driver
- Clarification of DisCo properties and updates

soundwire: add module_sdw_driver helper macro
docs: soundwire: locking: fix tags for a code-block
soundwire: intel_init: add checks on link numbers

soundwire: intel: filter SoundWire controller device search
soundwire: cdns: Fix compilation error on arm64
Rename all fields with 'freq' as 'clk_freq' to follow the MIPI
specification and avoid confusion between bus clock and audio clocks.
No functionality change.

Found few more issues reported checkpatch on code alignment so fix those
as well in the intel module.

These two files are implicitly relying on an instance of including
module.h from <linux/acpi.h>.
Ideally, header files under include/linux shouldn't be adding
includes of other headers, in anticipation of their consumers,
but just the headers needed for the header itself to pass
parsing with CPP.
The module.h is particularly bad in this sense, as it itself does
include a whole bunch of other headers, due to the complexity of
module support.
Here, we make those includes explicit, in order to allow a future
removal of module.h from linux/acpi.h without causing build breakage.

the number of elements and size are inverted, fix.
This probably only worked because the number of properties is
hard-coded to 1.

The snd_soc_dai_ops structures are only stored in the ops field of a
snd_soc_dai_driver structure, so make the snd_soc_dai_ops structures
const as well.

Currently the return status ret is being checked but it has not been
updated since the previous check on ret. It appears that assignment of
ret from return status of the call to sdw_cdns_enable_interrupt was
accidentally ommited. Fix this.
