  Following series adds support to enable creation of multiple representors
under one base device. There may be scenarios where port representors for
multiple PFs or VFs under PF are required and all these representor ports
created under a single pci device. Marvell CNXK port representor solution
is designed around this scenario where all representors are backed by a
single switch device.

Earlier this change was implemented as part of the Marvell CNXK port
representor series but after suggestions from Thomas we would like
to propose these changes in common code.

V4:
- Used MT safe strtok_r in place of strtok
- Reworded some comments

V3:
- Fix duplicate representor devarg key handling logic

V2:
- Updated the multiple representor devarg pattern to list
i.e. representor=[pf[0-1],pf2vf[1,2-3],[4-5]]
- Introduced size of array as third argument to rte_eth_devargs_parse()
to avoid array corruption
- Squashed separate document patch
