Introduce type constant. Introduce cast macro and drop dummy busdev
field used with FROM_SYSBUS() that would've broken SYS_BUS_DEVICE().
Avoid accessing parent fields directly.

During the QOM migration they were amended with further info but this is
no longer the case. All static TypeInfos can be const these days.

Replace device_init() with generalized type_init().

While at it, unify naming convention: type_init([$prefix_]register_types)
Also, type_init() is a function, so add preceding blank line where
necessary and don't put a semicolon after the closing brace.

This was done in a mostly automated fashion.  I did it in three steps and then
rebased it into a single step which avoids repeatedly touching every file in
the tree.

The first step was a sed-based addition of the parent type to the subclass
registration functions.

The second step was another sed-based removal of subclass registration functions
while also adding virtual functions from the base class into a class_init
function as appropriate.

Finally, a python script was used to convert the DeviceInfo structures and
qdev_register_subclass functions to TypeInfo structures, class_init functions,
and type_register_static calls.

We are almost fully converted to QOM after this commit.

This converts three devices because apic and ioapic are subclasses of sysbus.
Converting subclasses independently of their base class is prohibitively hard.

The only reason we have bswap versions of the pci host code is that
most pci host devices are little endian. The ppc e500 is the only
odd one here, being big endian.

So let's directly pass the endianness down to the mmio layer and not
worry about it on the pci host layer.

introduce pci bridge library.
convert apb bridge and dec p2p bridge to use new pci bridge library.
save/restore is supported as a side effect.
This is also preparation for pci express root/upstream/downstream port.

Move pci bridge related code into pci_bridge.c from pci.c
for further enhancement. pci.c is big enough now, so split it out.
No code change but exporting some accesser functions.

In fact, few pci bridge functions stays in pci.c.
