Change device buf type

[primenumber]

Motivation and Context

device_output_buf has type BIN_CONV_OUTPUT, but the buf may contain values which has type QUANTIZED_PACKED.

device_input_buf and device_output_buf should contain only address information, so its type should be void* or similar type.

Description

• print_device_output_buf is no longer used and useless for now, so removed it.
