From: Farah Smith <farah.sm...@broadcom.com>
Add table scope to PF Mapping for SR and Wh+ devices.
Legacy devices require PF set of base addresses for EEM operation.
A table scope id is a logical construct and is mapped to the PF
associated with the communications channel used.
In the case of a VF, the parent PF is used.
