for the introduced get_pci_info() method in ACPI as it doesn't work reliably.
The new version should be more robust and efficient as it only resolves the
root bridge values once.
* Don't try to read and use the secondary bus register for the root bridge as
it isn't actually a normal bridge. We get the root bridge bus by using the
Base Bus Number (_BBN) method.
* Rewrite the logic to recurse down to all busses.
* Minor debug output changes to make the info more readable.

IO-APIC can be easily enabled to test it on various configurations. Note that
the previous default opt-out didn't work because the safemode options would not
be touched at all when not actually entering the boot menu.
Once IO-APIC is more broadly tested this can be removed again and the opt-out
option reenabled.

to PCI devices partly using the new ACPI interface and by using bridge config
information from PCI.
* Added lookup of matching device/pin combinations and update of the relevant
interrupt line variable via the new PCI module function. This means that the
Global System Interrupt (GSI) that is used after switching to the IO-APIC is
now stored in the PCI config space and drivers enumerating these devices will
now attach their interrupt handlers to the right IRQs.
* Resolve all relevant interrupt information directly into the irq_routing_entry
so that can be used as the single source for config information. This includes
resolving the current setting of any PCI link devices into the irq field that
represents a GSI now.
* Use that info to configure interrupts in arch_int.cpp and remove the logic
there.
* Some cleanup and added debug output.
This implements the final missing part for using IO-APICs and full APIC mode for
interrupt routing. Note that there is no quirk handling of any form, so this
may very well not work on some configurations. Note also that I have tested this
only on one machine so far. Once proper testing is done the default of disabling
the IO-APIC can be removed.

the base bus number and segment which is what we're using them for. It should
work generically, however I only tested it to look up PCI bridge devices.
The logic is a subset of what is done in AcpiEvPciConfigRegionSetup when setting
up the operation region for a PCI device.

the cached pci_info and writes the new value into PCI config space. Drivers
using either mechanism to enumerate devices will therefore get the updated
value.

layout API, we probably can just phase it out after a while.
* Introduced new constructors, and added missing flags to one of them to make
it more convenient to use.

* Some automatic whitespace cleanup.
This makes the interrupt model change via kernel actually work.

correct PCI IRQ routing table for that mode. With this, we finally get the right
PIRQ <-> Global System Interrupt mapping and can therefore program the right
IO APIC entries. The only missing part now is to fix up the pci_info of the
devices with the then active GSI.

* This should close#5786, but YMMV - comments and corrections welcome!

* The irq values we get from ACPICA are already converted, remove the wrong
extra conversion from bitfield to irq number.
* Add and handle extended irq structures.
* Disable the legacy PIC when done configuring the IOAPIC. Since during that
configuration the ACPI module is initialized, the ACPI SCI is still enabled
in the PIC instead of the IOAPIC. We'll have to delay that routing in the
ACPI module for it to work.
* Correctly handle the fixed IRQ case for the PCI interrupt routing (hopefully).
* Actually allow for enumeration of possible IRQ settings. Not yet used though.
All of this brings us a bit closer, though it still won't work for PCI
interrupts. ISA interrupts work fine through the IOAPIC as far as my hardware
goes, but PCI interrupts are connected to dedicated IOAPIC pins and I still
haven't figured out how to determine their exact routing.
