switchtec: Use generic PCI Vendor ID and Class Code 

Move the Microsemi Switchtec PCI Vendor ID (same as
PCI_VENDOR_ID_PMC_Sierra) to pci_ids.h.   Also, replace Microsemi class
constants with the standard PCI definitions.

[bhelgaas: restore SPDX (I assume it was removed by mistake), remove
device ID definitions]
