[PATCH 00/12] hw/isa/vt82c686: Implement relocation and toggling of SuperI/O functions |

This series implements relocation of the SuperI/O functions of the VIA south
bridges which resolves some FIXME's. It is part of my via-apollo-pro-133t
branch [1] which is an extension of bringing the VIA south bridges to the PC
machine [2]. This branch is able to run some real-world X86 BIOSes in the hope
that it allows us to form a better understanding of the real vt82c686b devices.
Implementing relocation and toggling of the SuperI/O functions is one step to
make these BIOSes run without error messages, so here we go.
The series is structured as follows: Patches 1-8 export the device structs of
the ISA serial and FDC devices. This is used later in the series to access the
I/O regions for relocation and toggling. As part of the exposal the MAINTAINERS
file gets a fix for the serial headers.
Inspired by the memory API patches 9-11 add two convenience functions to the
portio_list API to toggle and relocate portio lists. Patch 9 is a preparation
for that which removes some redundancies which otherwise had to be dealt with
during relocation.
Patch 12 finally implements the main feature which required adaption of the
pegasos2 sources, otherwise the machine wouldn't boot when given no bios.
Testing done:
* make check
* make check-avocado
* Run MorphOS on pegasos2 with and without pegasos2.rom
* Run Linux on amigaone
* Run real-world BIOSes on via-apollo-pro-133t branch
* Start rescue-yl on fuloong2e
