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.

When guest reset, we need to halt secondary cpus until guest kick them.
This already works for tcg. The patch add the support for kvm.

CPUs that are not the boot CPU need to run in spinning code to check if they
should run off to execute and if so where to jump to. This usually happens
by leaving secondary CPUs looping and checking if some variable in memory
changed.
In an environment like Qemu however we can be more clever. We can just export
the spin table the primary CPU modifies as MMIO region that would event based
wake up the respective secondary CPUs. That saves us quite some cycles while
the secondary CPUs are not up yet.
So this patch adds a PV device that simply exports the spinning table into the
guest and thus allows the primary CPU to wake up secondary ones.

---
v1 -> v2:
- change into MMIO scheme
- map the secondary NIP instead of 0 1:1
- only map 64MB for TLB, same as u-boot
- prepare code for 64-bit spinnings
v2 -> v3:
- remove r6
- set MAS2_M
- map EA 0
- use second TLB1 entry
v3 -> v4:
- change to memoryops
v4 -> v5:
- fix endianness bugs
v5 -> v6:
- add header
