net/nfp: fix address always related with PF ID 0

[ upstream commit 467370c93d73267c1d4417bff975cf812b878f48 ]

Now the PCIE configure bar address is always related with PF ID 0.
For the NIC with multiple PCI device, this will lead the host crash.
Fix this problem by make the PCIE configure bar address related with
the PF ID.

Fixes: c7e9729 ("net/nfp: support CPP")
