copier: check gateway type for converter function

Adjust sample type based on hw feature. It only affects s24/c32 patterns
since the valid 24bits sample can be in LSB or MSB part of 32 bits
container.

We don't support other patterns like s16/c32 now since they are rarely used
by gateway and can be added if they are used.
