[PATCH] PCI: per-platform IA64_{FIRST,LAST}_DEVICE_VECTOR definitions
Abstract IA64_FIRST_DEVICE_VECTOR/IA64_LAST_DEVICE_VECTOR since SN platforms
use a subset of the IA64 range. Implement this by making the above macros
global variables which the platform can override in it setup code.
Also add a reserve_irq_vector() routine used by SN to mark a vector's as
in-use when that weren't allocated through assign_irq_vector().
