[IA64] Update comment to describe modes set in default control register.
Christian Hildner pointed out that the comment did not match what the code does in cpu_init() when we set up the default control register. Patch based on suggestions from Ken Chen. Signed-off-by: Tony Luck <tony.luck@intel.com>
