[PATCH] disable lost tick compensation before TSCs are synced

Avoid lost tick compensation early in boot before the TSCs are
synchronized.  Currently timekeeping is enabled before the TSCs are
synchronized, thus when the TSCs are synched (reset to zero), it appears
that a number of lost ticks have occurred.  This can cause premature expiry
of timers and in extreme cases can cause the soft lockup detection to fire.

This resolves issues reported by Andy Whitcroft as well as bug #5366
reported by Tim Mann.
