hw/char/parallel-isa: Implement relocation and enabling/disabling for TYPE_ISA_PARALLEL

The real SuperI/O chips emulated by QEMU allow for relocating and enabling or
disabling their SuperI/O functions via software. So far this is not implemented.
Prepare for that by adding isa_parallel_set_{enabled,iobase}.

Include hw/qdev-properties.h less

In my "build everything" tree, changing hw/qdev-properties.h triggers
a recompile of some 2700 out of 6600 objects (not counting tests and
objects that don't depend on qemu/osdep.h).

Many places including hw/qdev-properties.h (directly or via hw/qdev.h)
actually need only hw/qdev-core.h. Include hw/qdev-core.h there
instead.

hw/qdev.h is actually pointless: all it does is include hw/qdev-core.h
and hw/qdev-properties.h, which in turn includes hw/qdev-core.h.
Replace the remaining uses of hw/qdev.h by hw/qdev-properties.h.

While there, delete a few superfluous inclusions of hw/qdev-core.h.

Touching hw/qdev-properties.h now recompiles some 1200 objects.

hw/char/parallel: Make it possible to compile also without CONFIG_PARALLEL

For the downstream distribution of QEMU, we want to compile without
CONFIG_PARALLEL. Commit 9157eee1b1c076ff3 already moved the function
parallel_hds_isa_init() (which is still required for linking) into a file
that is included anyway, but commit bb3d5ea858e7f888563a moved it
to a separate file which is only compiled again if CONFIG_PARALLEL is
set. To be able to link QEMU again without CONFIG_PARALLEL, the file
should be considered for linking for all targets that have CONFIG_ISA_BUS.
And while we're at it, add a proper comment in there with the rationale
for the separate file.
