This patch enables use of 8-bit unsigned, A-law, and mu-law sample formats with IPC4 SOF. The ipc4-topology.h is updated with IPC4 sample types. The purpose is to to convert ALSA types to IPC4 types. The functions of_ipc4_update_hw_params(), sof_ipc4_get_valid_bits(), and new function sof_ipc4_get_sample_type() are updated to handle the sample type conversions. The function sof_ipc4_prepare_copier_module() is updated to set the DMA SCS bit for all non 32 bits sample types. The change to function sof_ipc4_get_valid_bits() returns 8 bits for these ALSA formats. The change to function sof_ipc4_prepare_copier_module() is needed to handle properly all non 32-bit formats with SCS bit set. To support playback with new 8 bits types, the sof_ipc4_init_input_audio_fmt() function is updated to get the sample type and use it in search for copier input pin format. To support capture, the sof_ipc4_init_output_audio_fmt() is updated similarly. Since the function uses separate out_ref_type argument, instead of single parameters struct, the out_ref_type needs to be added to every user of the function. Therefore functions sof_ipc4_prepare_copier_module(), sof_ipc4_prepare_gain_module(), sof_ipc4_prepare_mixer_module(), sof_ipc4_prepare_src_module(), and sof_ipc4_prepare_process_module() are updated to set the out_ref_type.

This patch adds support for FLOAT_LE ALSA type for playback and capture for IPC4 systems. Functions sof_ipc4_update_hw_params(), sof_ipc4_get_valid_bits() and sof_ipc4_get_sample_type() are updated to handle SOF_IPC4_TYPE_FLOAT and SNDRV_PCM_FORMAT_FLOAT_LE.
