ASoC: SOF: ipc4-topology: Modify the type of available input/output formats

Introduce a new struct sof_ipc4_pin_format which contains the pin index
and the buffer size. Replace the type of available input/output audio
formats in struct sof_ipc4_available_audio_format with this new struct
type and rename them to input_pin_fmts and output_pin_fmts.

Also, add a new token, SOF_TKN_CAVS_AUDIO_FORMAT_PIN_INDEX that will be
used to parse the pin index for the audio format from topology.
Currently we only set the audio format for Pin 0 in topology, so the
default value will be 0 for all audio formats.

Finally, parse the pin_index and the input/output buffer sizes
along with audio formats into the pin_format arrays in struct
sof_ipc4_available_audio_format. This makes the base_config array in struct
sof_ipc4_available_audio_format redundant. So remove it. This change
will allow the addition of audio formats for the non-zero pins in
topology transparent to the topology parser in the kernel.
