[build] Avoid generating ROMs with "match-any" vendor or device IDs

Browse Source 
A PCI_ROM() entry containing a vendor or device ID of PCI_ANY_ID
(0xffff) indicates to pci_find_driver() that the entry's vendor or
device ID should be ignored when matching against the device's vendor
or device ID.  It does not represent a PCI ROM that should be built.
