Pull request overview
This PR converts the smart_amp component from the legacy component driver model to the new module adapter framework, removing dependencies on component-specific APIs and updating to use processing_module infrastructure.
Changes:
- Replaced component driver interface with module adapter interface
- Updated memory allocation from legacy
rballoc/rfreeto module APImod_alloc/mod_free - Migrated IPC command handlers to new configuration APIs (
set_configuration/get_configuration)

NOTE: This change has not been tested in any functional setup
For smart_amp to remain compatible with developing SOF it has to be
converted to use module API. The component API as such does not allow
llext loading or user-space usage. However, its unlikely the module
will work out of the box after this change, but in any case this
should make it easier to take smart_amp again into use.
This patch converts this component to module adapter API.
- New() becomes simpler init()
- Params() is handled in module adapter, in init()
"mod->verify_params_flags = BUFF_PARAMS_CHANNELS;" replaces
smart_amp_verify_params()
- Channels check in params() is placed to separate function
smart_amp_ipc4_params() to be called from prepare()
- cmd() handler is changed to module adapter client style with
smart_amp_set_configuration() and smart_amp_get_configuration().
- smart_amp_copy() becomes module API smart_amp_process() function
- smart_amo_prepare() picks sources and sink and does other
preparations for processing
- smart_amp_trigger() does the same thing as before, zeroes feedback
buffer at playback start
- Preliminary IPC4 support added

The llext stuff is still missing, but I had to go to sleep.
Anyway the conversion is ready AFAICT. The llext stuff can be added in separate PR.
