Hi.

I've made a patch, updating sparc64/sun4v timer driver to utilize new MI
event timer infrastructure. There are several benefits:
 - unified interfaces and behavior with other platforms,
 - support for timer in one-shot mode,
 - more timer hardware can be easily supported (if there any).
Code works for me on UP sparc64 (SunBlade 100) and builds on sun4v.
Should work on SMP, but I can't test it.

Patch for HEAD can be found here:
http://people.freebsd.org/~mav/timers_sparc.patch

Any comments?
