Subject: [PATCH v3 0/6] tty: serial: 8250: Changes of MOXA PCIe boards in 8250_pci.c

These patch series do some changes to MOXA PCIe boards in 8250_pci.c,
including:

- Modify MOXA enum name within 8250_pci.c
- Cleanup MOXA configurations within 8250_pci.c
- Relocate macros within 8250_pci.c
- Add support for MOXA Mini PCIe boards
- Fix MOXA RS422/RS485 boards not function by default
- Add support for MOXA PCIe boards to switch between different serial
  interfaces

Each patch depends on previous one.

---
Changes in v3:
- Add reviewer tag in first 4 patches.
- [PATCH v3 2/6]:
	- Make commit message clearer.
- [PATCH v3 5/6]:
	- Delete pci_moxa_match_x3xx() function.
	- Introduce pci_moxa_match_second_digit() function.
- [PATCH v3 6/6]:
	- Delete pci_moxa_match_x1xx() function.
	- Replace pci_moxa_match_x1xx() and pci_moxa_match_x3xx() with
	  pci_moxa_match_second_digit().
	- Add comment at pci_moxa_rs485_config().
	- Revise comment and return value where device not support RS232
	  interface.

Changes in v2:
- Split cleanup patch into first 2 patches of this patch series.
- Reposition macro list to the top of the code.
- Use PCI_VDEVICE() instead of PCI_DEVICE() in serial_pci_tbl[].
- Replace some C99 types with kernel types.
- Introduce functions for checking device ID pattern.
- Replace magic constant with BIT().
- Sort macros into pre-existing macro list.
- Rewrite set_interface condition architecture.
- Utilize unused flag to represent RS422 interface instead of adding a
  new one.
