soundwire: cadence: add BTP/BRA helpers to format data

The Cadence IP expects a specific format (detailed in the
Documentation). Add helpers to copy the data into the DMA buffer.

The crc8 table is for now only used by the Cadence driver. This table
might be moved to a common module at a later point if needed by other
controller implementations.

soundwire: slave: lookup SDCA version and functions

Use SDCA helpers to get the basic information and store it in the

drivers to register sub-devices for each Function.

When platforms are not based on ACPI the helpers do absolutely
nothing.

soundwire: intel_ace2x: fix SND_SOC_SOF_HDA_MLINK dependency

The ace2x driver can be build with or without mlink support, but
when SND_SOC_SOF_HDA_MLINK is set to =m and soundwire is built-in,
it fails with a link error:

ld.lld: error: undefined symbol: hdac_bus_eml_sdw_wait_syncpu_unlocked
>>> referenced by intel_ace2x.c
>>> drivers/soundwire/intel_ace2x.o:(intel_link_power_up) in archive vmlinux.a

>>> referenced by intel_ace2x.c
>>> drivers/soundwire/intel_ace2x.o:(intel_sync_arm) in archive vmlinux.a

Add a Kconfig dependency that prevents that broken configuration but
still allows soundwire to be a loadable module instead.

soundwire: intel: move to auxiliary bus

Now that the auxiliary_bus exists, there's no reason to use platform
devices as children of a PCI device any longer.

This patch refactors the code by extending a basic auxiliary device
with Intel link-specific structures that need to be passed between
controller and link levels. This refactoring is much cleaner with no
need for cross-pointers between device and link structures.

Note that the auxiliary bus API has separate init and add steps, which
requires more attention in the error unwinding paths. The main loop
needs to deal with kfree() and auxiliary_device_uninit() for the
current iteration before jumping to the common label which releases
everything allocated in prior iterations.

soundwire: Add generic bandwidth allocation algorithm

This algorithm computes bus parameters like clock frequency, frame
shape and port transport parameters based on active stream(s) running
on the bus.

Developers can also implement their own .compute_params() callback for
specific resource management algorithm, and set if before calling
sdw_add_bus_master()

Credits: this patch is based on an earlier internal contribution by
Vinod Koul, Sanyog Kale, Shreyas Nc and Hardik Shah. All hard-coded
values were removed from the initial contribution to use BIOS
information instead.
