[dpdk-dev] [PATCH v4 17/52] common/cnxk: add base nix support

[Nithin Dabilpuram <ndabilpuram@marvell.com>]

From: Jerin Jacob <jerinj@marvell.com>

Add base nix support as ROC(Rest of Chip) API which will
be used by generic ETHDEV PMD(net/cnxk).

This patch adds support to device init, fini, resource
alloc and free API which sets up a ETHDEV PCI device of either
CN9K or CN10K Marvell SoC.
