serial: Add support for Advantech PCI-1611U card

commit d2b00516de0e1d696724247098f6733a6ea53908 upstream.

Add support for Advantech PCI-1611U card

Advantech provides opensource drivers for this and many others card
based on legacy copy of 8250_pci driver called adv950

It is hard to maintain to run as out of tree module on newer kernels.
Just adding PCI ID to kernel 8250_pci works perfect.
