Extend RSS offload types for octeontx2. Add support to select
L3 SRC, L3 DST, L4 SRC and L4 DST for RSS calculation.

Add support to select L3 SRC or DST only, L4 SRC or DST only for RSS
calculation.

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.

Should n't we update the struct
rte_eth_dev_info::flow_type_rss_offloads to show this capability to
the driver. Please check other drivers.

Verified with testpmd. I need to update the supported RSS offloads. Will send V2.
