  - Handle the case where x2APIC is enabled and locked by the BIOS on a
    kernel with CONFIG_X86_X2APIC=n gracefully. Instead of a panic which
    does not make it to the graphical console during very early boot,
    simply disable the local APIC completely and boot with the PIC and very
    limited functionality, which allows to diagnose the issue.

  - Convert x86 APIC device tree bindings to YAML

  - Extend x86 APIC device tree bindings to configure interrupt delivery
    mode and handle this in during init. This allows to boot with device
    tree on platforms which lack a legacy PIC.
