IPC4 params do not provide a PCM sampling rate that is dynamically selected based on the mode (PULL/PUSH). Instead, the received params contain only a copy of the source rate already stored in ipc4_asrc_module_cfg. As a result, mode-dependent validation can trigger a bogus error. Fix this by splitting params validation into IPC protocol-specific functions. Signed-off-by: Wojciech Jablonski <wojciech.jablonski@intel.com>

Pull request overview
This pull request fixes incorrect runtime PCM rate validation in the ASRC module by making stream-parameter validation IPC-protocol specific, avoiding bogus errors for IPC4 where the runtime params rate is not mode-dependent (PULL/PUSH) in the same way as IPC3.
Changes:
- Split ASRC stream params verification into
asrc_verify_stream_params()with IPC3/IPC4-specific implementations. - Update ASRC params handling to call the new verification function and keep buffer parameter verification (
comp_verify_params) inasrc.c. - Add the new verification function prototype to the ASRC public header.

| File | Description |
|---|---|
| src/audio/asrc/asrc.h | Adds the asrc_verify_stream_params() declaration used by the common ASRC params path. |
| src/audio/asrc/asrc.c | Replaces the old monolithic verification with IPC-specific verification + comp_verify_params(). |
| src/audio/asrc/asrc_ipc4.c | Implements IPC4 verification as a no-op to avoid mode-dependent false failures. |
| src/audio/asrc/asrc_ipc3.c | Moves the mode-dependent PCM rate validation logic into the IPC3-specific implementation. |
