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
ld.lld: error: undefined symbol: sdw_amd_exit
>>> 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.

The new IPC4 version is only supported by Intel platforms, iMX, AMD and
MediaTek only uses the standard SOF IPC.
There is no need for these platforms to build kernel support for IPC4 as
it is just dead code for them.
SND_SOC_SOF_IPC3 and SND_SOC_SOF_INTEL_IPC4 is introduced to allow compile
time selection and exclusion of IPC implementations.
To avoid randconfig failures add also support for runtime selection of
the IPC ops in ipc.c based on sdev->pdata->ipc_type
