[IA64] ITC: Reduce rating for ITC clock if ITCs are drifty
Make sure to reduce the rating of the ITC clock if ITCs are drifty. If they are drifting then we have not synchronized the ITC values, nor are we doing the jitter compensation (useless since drift may increase the differentials arbitrarily). Without this patch it is possible that the ITC clock becomes selected as the system clock on systems with drifty ITCs which will result in nanosleep hanging. One can still select the itc clock manually on such systems via clocksource=itc (Produces nice hangs on SGI Altix.)
