qed: Add CONFIG_QED_SRIOV
Add support for a new Kconfig option for qed* driver which would allow
[eventually] the support in VFs.
This patch adds the necessary logic in the PF to learn about the possible
VFs it will have to support [Based on PCI configuration space and HW],
and prepare a database with an entry per-VF as infrastructure for future
interaction with said VFs.
