History
Tobias Diedrich bafdc39d1c serial: 8250_pci: Add Realtek 816a and 816b 
commit 3c5a87be17 upstream.

These serial ports are exposed by the OOB-management-engine on
RealManage-enabled network cards (e.g. AMD DASH enabled systems using
Realtek cards).

Because these have 3 BARs, they fail the "num_iomem <= 1" check in
serial_pci_guess_board.

I've manually checked the two IOMEM regions and BAR 2 doesn't seem to
respond to reads, but BAR 4 seems to be an MMIO version of the IO ports
(untested).

With this change, the ports are detected:
0000:02:00.1: ttyS0 at I/O 0x2200 (irq = 82, base_baud = 115200) is a 16550A
0000:02:00.2: ttyS1 at I/O 0x2100 (irq = 55, base_baud = 115200) is a 16550A

lspci output:
