qdev: register all types natively through QEMU Object Model

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...

isa: pic: convert to QEMU Object Model

This converts two devices at once because PIC subclasses ISA and converting
subclasses independently is extremely hard.

isa: give ISABus/ISADevice to isa_create(), isa_bus_irqs() and isa_get_irq() functions

NULL is a valid bus/device, so there is no change in behaviour.

pc: Generalize ISA IRQs to GSIs

The ISA bus IRQ range is 0..15. What isa_irq_handler and IsaIrqState are
actually dealing with are the Global System Interrupts. Refactor the
code to clarify this.

isa: Tidy support code for isabus_get_fw_dev_path

The only user of ISADevice.ioports is isabus_get_fw_dev_path, and it
only looks at the first entry of the array. Which suggests that this
entire array+sort operation can be replaced by a simple minimum.

isa-bus: Remove bogus IRQ sharing check

Nothing prevented IRQ sharing on the ISA bus in principle. Not all
boards supported this, neither each and every card nor driver and OS.
Still, there existed valid IRQ sharing scenarios, (at least) two of them
can also be found in QEMU: >2 PC UARTs and the PREP IDE buses....

Revert "Get rid of _t suffix"

In the very least, a change like this requires discussion on the list.

The naming convention is goofy and it causes a massive merge problem. Something
like this must be presented on the list first so people can provide input...

qdev: simplify isa irq assignments

isa-bus owns the isa irqs now, so it can hand them out directly.
There is no need for the separate isa_connect_irqs step, drop it.

Also hard-code isa interrupts which can't be configured anyway.

qdev: drop iobase properties from isa bus

Lot of ISA devices work at fixed addresses, so having iobase
as bus property doesn't make much sense. Devices which can
have different iobases will get a device property.

Also simply hard-code stuff which can't be configured anyway....

qdev: add return value to init() callbacks.

Sorry folks, but it has to be. One more of these invasive qdev patches.

We have a serious design bug in the qdev interface: device init
callbacks can't signal failure because the init() callback has no
return value. This patch fixes it....
