ASoC: SOF: ipc4-topology: Convert FLOAT to S32 during blob selection
commit 816f291fc23f325d31509d0e97873249ad75ae9a upstream.
SSP/DMIC blobs have no support for FLOAT type, they are using S32 on data
bus.
Convert the format from FLOAT_LE to S32_LE to make sure that the correct
format is used within the path.
FLOAT conversion will be done on the host side (or within the path).
Fixes: f7c41911ad74 ("ASoC: SOF: ipc4-topology: Add support for float sample type")
