ASoC: SOF: ipc4-topology: Add support for float sample 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.
