common/cnxk: support NIX LSO and misc utils

Browse Source 
Add support to create LSO formats for TCP segmentation offload
for IPv4/IPv6, tunnel and non-tunnel protocols. Tunnel protocol
support is for GRE and UDP based tunnel protocols.

This patch also adds other helper API to retrieve eeprom info
and configure Rx for different switch headers.
