ASoC: SOF: ipc4-topology: Allocate ref_params on stack

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

sound/soc/sof/ipc4-topology.c:1800:1: error: stack frame size (1288) exceeds limit (1024) in 'sof_ipc4_prepare_copier_module' [-Werror,-Wframe-larger-than]
 1800 | sof_ipc4_prepare_copier_module(struct snd_sof_widget *swidget,
      | ^

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).
