SGI Altix mmtimer: allow larger number of timers per node

SGI Altix mmtimer: allow larger number of timers per node

The purpose of this patch to the SGI Altix specific mmtimer (posix timer)
driver is to allow a virtually infinite number of timers to be set per
node.

Timers will now be kept on a sorted per-node list and a single node-based
hardware comparator is used to trigger the next timer.
