      Introduce SPR_KAIVB for interrupt vector table relocation. · d491878d
      Jonathan Currier authored
      The PowerPC ISA allows for some amount of interrupt vector table
      relocation, but it is defined in the context of a hypervisor.
      
      Kestrel/microwatt does not implement hypervisor, and so lacks the
      associated registers and logic.
      
      Introduce a simple register to set the interrupt vector table base.
      Kestrel arch interrupt vector base: KAIVB.
      
      Provides mapping of 48 bits (bits 14:61) of a 16KiB aligned table.
