[SERIAL] add TP560 data/fax/modem support

Patch from Bjorn Helgaas

Claim Topic TP560 data/fax/voice modem.  This device reports as class 0x0780,
so we don't claim it by default:

        00:0d.0 Class 0780: 151f:0000
                Subsystem: 151f:0000
                Interrupt: pin A routed to IRQ 11
                Region 0: I/O ports at a400 [size=8]
        00: 1f 15 00 00 01 00 00 02 00 00 80 07 00 00 00 00
        10: 01 a4 00 00 00 00 00 00 00 00 00 00 00 00 00 00
        20: 00 00 00 00 00 00 00 00 00 00 00 00 1f 15 00 00
        30: 00 00 00 00 00 00 00 00 00 00 00 00 0b 01 00 00

Some rc.serial scripts extract IRQ and I/O port information from
/proc/pci and stuff it into an unused port using setserial.  That
doesn't work reliably anymore because pci_enable_device() is never
called, so the IRQ may not be enabled.

Thanks to Evan Clarke for reporting and helping debug this problem.
