Merge branch 'nfp-support-corigine-pcie-vendor-id'

Simon Horman says:

====================
nfp: support Corigine PCIE vendor ID

Historically the nfp driver has supported NFP chips with Netronome's
PCIE vendor ID. This patch extends the driver to also support NFP
chips, which at this point are assumed to be otherwise identical from
a software perspective, that have Corigine's PCIE vendor ID (0x1da8).

This patchset begins by cleaning up strings to make them:
* Vendor neutral for the NFP chip
* Relate to Corigine for the driver itself

It then adds support to the driver for the Corigine's PCIE vendor ID
