dpa_offload: Switch DPA Classifier from using fmd/crc64 to using lib/crc64
The DPA Classifier is computing a CRC64 ECMA by using the Frame
Manager driver. Because the CRC64 ECMA generic module was recently
accepted in linux/lib it will now use this CRC64 module instead of
the implementation from FMan driver.
