This is an effort to clean up the hw/riscv directory. Ideally it
should only contain the RISC-V SoC / machine codes plus generic
codes. Let's move sifive_test model to hw/misc directory.

The kernel does a 16-bit write when powering off the machine, which
was allowed before commit 5d971f9e67 ("memory: Revert "memory: accept
mismatching sizes in memory_region_access_valid""). Make min_access_size
match reality so that the machine can shut down properly now.

This is the transformation explained in the commit before previous.

The first rule exempts hw/arm/highbank.c, because it matches along two
control flow paths there, with different @type_name. Covered by the
next commit's manual conversions.
Missing #include "qapi/error.h" added manually.

Commit a27bd6c779ba ("Include hw/qdev-properties.h less") wrongly
added "hw/hw.h" to sifive_prci.c and sifive_test.c.
Another inclusion of "hw/hw.h" was later added via
commit 650d103d3ea9 ("Include hw/hw.h exactly where needed"), that
resulted in duplicated inclusion of "hw/hw.h".

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.

In my "build everything" tree, changing hw/hw.h triggers a recompile
of some 2600 out of 6600 objects (not counting tests and objects that
don't depend on qemu/osdep.h).
The previous commits have left only the declaration of hw_error() in
hw/hw.h. This permits dropping most of its inclusions. Touching it
now recompiles less than 200 objects.
