    Pull x86 apic update from Thomas Gleixner:
     "A set of changes for the x86 APIC code:
    
       - 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"
