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).
