tty: serial: 8250: Add SystemBase Multi I/O cards

Add support for the SystemBase Multi I/O serial cards, which are
"compatible" with a standard 16550A controllers, except that they need
to have their interrupts enabled in a proprietary way.

Tested with a Delock "Serial PCI Express x1 Card 8x Serial RS-232".
