serial: 8250_pci: replace PCI_VENDOR_ID_ADDIDATA_OLD

PCI_VENDOR_ID_ADDIDATA_OLD has the same value (0x10e8) as
PCI_VENDOR_ID_AMCC in <linux/pci_ids.h>.  The vender ID is actually
assigned to Applied Micro Circuits Corporation.  The 8250_pci driver
uses PCI_VENDOR_ID_ADDIDATA_OLD in the lists of quirks and PCI IDs for
the ADDI-DATA APCI-7800 card.  Change it to use the more accurate
PCI_VENDOR_ID_AMCC.
