topology2: deep buffer: use 32 bits to align with other pipelines 

Now deep buffer uses S24_LE but other pipelines use S32_LE internal format
. Chrome team found a bug that deep buffer can't work well with I2S codec
since fw only support S32_LE for I2S now.

This patch will use S32_LE to align with current requirement
