According to Amlogic datasheets for the SoCs supported by this driver, the
maximum bit clock rate is 100MHz.

The tdm interface allows the rates listed by the DAI driver, regardless of
the number slots or their width. However, these will impact the bit clock
rate.

Hitting the 100MHz limit is very unlikely for most use cases but it is
possible.

For example with 32 slots / 32 bits wide, the maximum rate is no longer
384kHz but ~96kHz.

Add the constraint accordingly if the component is not already active.
If it is active, the rate is already constrained by the first stream rate.

By default, when mclk-fs is not provided, the tdm-interface driver
requests an MCLK that is 4x the bit clock, SCLK.

However there is no justification for this:

* If the codec needs MCLK for its operation, mclk-fs is expected to be set
  according to the codec requirements.
* If the codec does not need MCLK the minimum is 2 * SCLK, because this is
  minimum the divider between SCLK and MCLK can do.

Multiplying by 4 may cause problems because the PLL limit may be reached
sooner than it should, so use 2x instead.

Create a new library for code that is used by multiple Cirrus Logic
amps. This initially implements extracting amp calibration data
from EFI and writing it to firmware controls.

During factory calibration of built-in speakers the firmware
calibration constants are stored in an EFI file. The file contains
an array of calibration constants for each of the speakers.
cs_amp_get_calibration_data() searches for an entry matching the
requested UID stamp, otherwise by array index. If the data is found in
EFI the constants for that speaker are copied back to the caller.

If EFI is not enabled, the cs_amp_get_calibration_data() implementation
will compile to simply return -ENOENT and the linker can drop the code.

The code to write calibration controls uses cs_dsp. Building of cs_dsp
is not forced. Instead, the code will compile away the calls to
cs_dsp if cs_dsp is not reachable.

This strategy of conditional code allows cs-amp-lib to be shared by
multiple drivers without forcing inclusion of other modules that might
be unnecessary.

The calls to efi.get_variable() and cs_dsp are in small wrapper
functions. This is so that a KUNIT_STATIC_STUB_REDIRECT can be added in
a future patch to redirect these calls to replacement functions for
KUnit testing.

Merge series from Cezary Rojewski <cezary.rojewski@intel.com>:

The avs-driver continues to be utilized on more recent Intel machines.
As TGL-based (cAVS 2.5) e.g.: RPL, inherit most of the functionality
from previous platforms:

SKL <- APL <- CNL <- ICL <- TGL

rather than putting everything into a single file, the platform-specific
bits are split into cnl/icl/tgl.c files instead. Makes the division clear
and code easier to maintain.

Layout of the patchset:

First are two changes combined together address the sound-clipping
problem, present when only one stream is running - specifically one
CAPTURE stream.

Follow up is naming-scheme adjustment for some of the existing functions
what improves code incohesiveness. As existing IPC/IRQ code operates
solely on cAVS 1.5 architecture, it needs no abstraction. The situation
changes when newer platforms come into the picture. Thus the next two
patches abstract the existing IPC/IRQ handlers so that majority of the
common code can be re-used.

The ICCMAX change stands out a bit - the AudioDSP firmware loading
procedure differs on ICL-based platforms (and onwards) and having a
separate commit makes the situation clear to the developers who are
going to support the solution from LTS perspective. For that reason
I decided not to merge it into the commit introducing the icl.c file.

Update board selection with tables specifying supported I2S
configurations. DMIC/HDAudio board selection require no update as
dmic/hdaudio machine boards are generic and not tied to any specific
codec.

The soundwire-amd driver has a bit of a layering violation requiring
the SOF driver to directly call into its exported symbols rather than
through an abstraction.

The SND_SOC_SOF_AMD_SOUNDWIRE Kconfig symbol tries to deal with the
dependency by selecting SOUNDWIRE_AMD in a complicated set of conditions,
but gets it wrong for a configuration involving SND_SOC_SOF_AMD_COMMON=y,
SND_SOC_SOF_AMD_ACP63=m, and SND_SOC_SOF_AMD_SOUNDWIRE_LINK_BASELINE=m
SOUNDWIRE_AMD=m, which results in a link failure:

ld.lld: error: undefined symbol: sdw_amd_get_slave_info
>>> referenced by acp-common.c
ld.lld: error: undefined symbol: amd_sdw_scan_controller
ld.lld: error: undefined symbol: sdw_amd_probe

>>> referenced by acp.c
>>>               sound/soc/sof/amd/acp.o:(amd_sof_acp_remove) in archive vmlinux.a

In essence, the SND_SOC_SOF_AMD_COMMON option cannot be built-in when
trying to link against a modular SOUNDWIRE_AMD driver.

Since CONFIG_SOUNDWIRE_AMD is a user-visible option, it really should
never be selected by another driver in the first place, so replace the
extra complexity with a normal Kconfig dependency in SND_SOC_SOF_AMD_SOUNDWIRE,
plus a top-level check that forbids any of the AMD SOF drivers from being
built-in with CONFIG_SOUNDWIRE_AMD=m.

In normal configs, they should all either be built-in or all loadable
modules anyway, so this simplification does not limit any real usecases.
