ASoC: SOF: ipc4-topology: Add a new field in struct sof_ipc4_available_audio_format

Add a new field, input_audio_fmts, in struct
sof_ipc4_available_audio_format and parse all the available input audio
formats into this new field and not into the base_config field. This is
preparation to remove the base_config array from the struct
sof_ipc4_available_audio_format.

This simplifies the sof_ipc4_init_audio_fmt()
function as the reference audio format for matching with input params
has the same size.
