PCI: octeontx-83: configure PKI sriov

commit cf36df95cf6539dc929d21b5665458e35405bfa6 from
git@git.assembla.com:cavium/WindRiver.linux.git

Octeontx 83xx has a unique case, where PKI does DMA with more than 1
streamids, but PKI is not a SRIOV/ multi function device.
this feet is acheived by giving 8 bit programmable streamid in QPG tables.
The intention was to allow differnt addressspace per GMID.
but in reality no one accepts a device doing DMA with random streamids.
and there is no infrsastrutre in Linux to allow this.

This patch address this problem by emulating SRIOV on PKI.
With this patch in place, applications will bind one of the PKI VF
to allow DMA.
