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 possiblyalso

the Maple in YKT.  Thanks to Jimi for his help in this matter.


Is the DPM change required?  I never saw any problems
here...  NAP and other power saving modes can cause
problems for sure (for example, on pre-970MP 970s, some
power saving modes require flushing the L2 before entering
that mode, etc.)
