2af3fc178e Introduce macro FDT_MAP_IRQ to map from an interrupt controller and 
interrupt pin pair to a global IRQ number. When multiple PICs exist
on a board, the interrupt pin alone is not unique.

This removes platform dependencies from <machine>/fdt.h for the benfit of
portability.

58158742f2 Import the common Flattened Device Tree infrastructure. 
o fdtbus(4) - the main abstract bus driver for all FDT-compliant systems. This
  is a direct replacement for the many incompatible bus drivers grouping
  integrated peripherals on embedded platforms (like obio(4), ocpbus(4) etc.)

o simplebus(4) - bus driver representing ePAPR style 'simple-bus' node, which
  is an umbrella device for most of the integrated peripherals on a typical
  system-on-chip device.

o Other components (common routines library, PCI node processing helper
  functions)
