octeontx2-af: extend RSS supported offload types
Add support to select L3 SRC or DST only, L4 SRC or DST only for RSS
calculation.
AF consumer may have requirement as we can select only SRC or DST data for
RSS calculation in L3, L4 layers. With this requirement there will be
following combinations, IPV[4,6]_SRC_ONLY, IPV[4,6]_DST_ONLY,
[TCP,UDP,SCTP]_SRC_ONLY, [TCP,UDP,SCTP]_DST_ONLY. So, instead of creating
a bit for each combination, we are using upper 4 bits (31:28) in the
flow_key_cfg to represent the SRC, DST selection. 31 => L3_SRC,
30 => L3_DST, 29 => L4_SRC, 28 => L4_DST. These won't be part of flow_cfg,
so that we don't need to change the existing ABI.
