[dpdk-dev] [PATCH v2 3/7] net/qede: define PCI config space specific osals

[Manish Chopra <manishc@marvell.com>]

This patch defines various PCI config space access APIs
in order to read and find IOV specific PCI capabilities.

With these definitions implemented, it enables the base
driver to do SR-IOV specific initialization and HW specific
configuration required from PF-PMD driver instance.
