PCI: Limit config space size for Netronome NFP6000 family

Browse source

commit 9f33a2ae59 upstream.

The NFP6000 has an erratum where reading/writing to PCI config space
addresses above 0x600 can cause the NFP to generate PCIe completion
timeouts.

Limit the NFP6000's config space size to 0x600 bytes.
