Currently the compiler (clang 19.1.7) is not happy about the size of the stack frame in sof_ipc4_prepare_copier_module:

Work around this by allocating ref_params on stack, as it looks the biggest variable on stack right now.
Note, this only happens when compile for 32-bit machines (x86_32 in my case).
I don't have better idea for fix, apart from somehow refactor this huge function. Thank you for the fix,
