net/dpaa2: use hash FLCTYPE only for LX2

Enabling hash results in FD requires setting DPNI_FLCTYPE_HASH in
dpni_set_offload API. Setting this FLCTYPE for DPNI sets the FD[SC]
to 0 for LS2 in the hardware thus disabling data/annotation stashing.
For LX2 this is fixed in hardware and thus hash result and parse
results can be received in FD using this option.
