Revert "versatile_pci: Put the host bridge PCI device at slot 29"

This reverts commit 5f37ef92b7690423ac6311d3c597e182fc5f8fe6.
It turns out that some kernels incorrectly depend on the
old QEMU behaviour of not putting the host PCI bridge device
where the hardware puts it, because they use a swizzling IRQ...

hw/pci-host/versatile.c: Update autodetect to detect newer kernels

Newer versatilepb kernels still don't get the IRQ mapping right
for the PCI controller, but they get it differently wrong (they add
a fixed +64 offset to everything they write to PCI_INTERRUPT_LINE)....

hw/pci-host/versatile.c: Provide property for forcing broken IRQ mapping

Although we try our best to automatically detect broken versions
of Linux which assume the old broken IRQ mapping we used to implement
for our model of the Versatile PCI controller, it turns out that...

hw/versatile_pci: Drop unnecessary vpb_pci_config_addr()

Drop the vpb_pci_config_addr() function -- it is unnecessary since
the size of the memory regions means the hwaddr is always within
the 24 bit size. (This function was probably a leftover from when...

versatile_pci: Implement the PCI controller's control registers

The versatile_pci PCI controller has a set of control registers which
handle the mapping between PCI and system address spaces. Implement
these registers (though for now they have no effect since we don't...

versatile_pci: Expose PCI memory space to system

The VersatilePB's PCI controller exposes the PCI memory space to the
system via three regions controlled by the mapping control registers.
Implement this so that guests can actually use MMIO-BAR PCI cards....

versatile_pci: Put the host bridge PCI device at slot 29

On real hardware the host bridge appears as a PCI device in slot 29,
so make QEMU put its host bridge in that slot too.

versatile_pci: Implement the correct PCI IRQ mapping

Implement the correct IRQ mapping for the Versatile PCI controller; it
differs between realview and versatile boards, but the previous QEMU
implementation was correct only for the first PCI card on a versatile...

versatile_pci: Update to realize and instance init functions

Update the Versatile PCI controller to use a realize function rather
than SysBusDevice::init. To reflect the fact that the 'realview_pci'
class is taking most of its implementation from 'versatile_pci' (and...

versatile_pci: Change to subclassing TYPE_PCI_HOST_BRIDGE

Change versatile_pci to subclass TYPE_PCI_HOST_BRIDGE and generally
handle PCI in a more QOM-like fashion.

versatile_pci: Use separate PCI I/O space rather than system I/O space

Rather than overloading the system I/O space (which doesn't even make
any sense on ARM) for PCI I/O, create an memory region in the PCI
controller and use that to represent the I/O space....

versatile_pci: Fix hardcoded tabs

There is just one line in this source file with a hardcoded tab
indent, so just fix it.

versatile_pci: Expose PCI I/O region on Versatile PB

Comments in the QEMU source code claim that the version of the PCI
controller on the VersatilePB board doesn't support the PCI I/O
region, but this is incorrect; expose that region, map it in the
correct location, and drop the misleading comments....
