[IA64] Rationalise Region Definitions
Currently, region numbers are defined in several files, with several names. For example, we have REGION_KERNEL in asm/page.h and RGN_KERNEL in pgtable.h We also have address definitions that should depend on the RGN_XXX macros, but are currently just long constants. The following patch reorganises all the definitions so that they have the same form (RGN_XXX), are in one place, and that addresses that depend on RGN_XXX are derived from them. (This is a necessary but not sufficient patch to allow UML-like operation on IA64). Thanks to David Mosberger for catching the change I missed in mmu_context.h.
