[XEN][POWERPC] Disable DPM until code is audited

Do not set the NAP and DPM bits in HID0 until we have had a chance to
audit the safe halt and idle loop code.  Not setting these bits allows
the model 884241X JS20 blade in TRL to boot correctly, and possibly also
the Maple in YKT.  Thanks to Jimi for his help in this matter.

Ack on the Maple. SMP is now "completely" stable on it.
Way to go Amos.
