This series extracts TYPE_SERIAL_MM into its own module and introduces a
dedicated header for TYPE_SERIAL_ISA. The result is that no board directly
depends on CONFIG_SERIAL or includes hw/char/serial.h any more.

The first two patches are only paritally reviewed and would benefit from a few
more R-b tags. Since the changes are mostly mechanical this may be "boring".

v2:
* Rebase onto master which eliminates patch "hw/ppc/Kconfig: Add missing
  SERIAL_ISA dependency to POWERNV machine" from the series (already applied)
* Drop patch "hw/char/serial: Remove unused funtion" (Zoltan)
* Add Mark's R-b and Andrew's T-b tags

Bernhard Beschow (3):
  hw: Remove unused inclusion of hw/char/serial.h
  hw/char/serial.h: Extract serial-isa.h
  hw/char: Extract serial-mm
