Subject: [PATCH 0/2] tty: serial: 8250: Adjustments of MOXA PCIe boards serial interface

This patch series do some adjustments about serial interface of MOXA
PCIe boards including:

- Fix MOXA RS422/RS485 PCIe boards not function by default
- Add support for MOXA PCIe boards to switch serial interface

The second patch depends on the first patch because the first patch
introduces a function called pci_moxa_set_interface() to set serial
interface and second patch utilize it with ioctl command "TIOCSRS485" to
switch serial interfaces.
