Clamp float data sent to HAL

When memcpying from float to float, we don't check for values
above unity, including NaN. In all other PCM cases, we clamp on either
side of the conversion.

Prior to writing to the HAL, check the data to insulate HALs
which may not tolerate invalid float PCM data gracefully.
