* shared/include/cpuIdent.c, shared/include/cpuIdent.h: Added support
	for e500v2.  Removed IVPR/IVOR/HWIVOR features since they are included
	in Book E.
	* new-exceptions/bspsupport/vectors.h,
	new-exceptions/bspsupport/ppc_exc.S,
	new-exceptions/bspsupport/ppc_exc_address.c,
	new-exceptions/bspsupport/ppc_exc_categories.c,
	new-exceptions/bspsupport/ppc_exc_initialize.c,
	new-exceptions/bspsupport/ppc_exc_prologue.c: Added support for
	e500v2.  Added exception vector defines for Book E types.  Removed
	e200 exception vector defines.  Added e500 exception vector defines.
	Unified IVOR calculation for e200 and e500 (e200z1 has hard wired
	IVOR values).
