Check a PCI device's class, subclass, and progif to figure out if it is
a USB4 NHI. Pink Sardine can thus be removed from nhi_identifiers as it
is a generic USB4 device.
nhi_identifiers is just kept for NHIs with quirks, notably pre-USB4
Thunderbolt chips.
Also, remove MODULE_PNP_INFO() for now. Will add this back once
thunderbolt driver is fully functional and tested.
