Here's an experimental patch that attempts to optimize the timer
reloading for gp_timer0. I don't know if this improves the latency
or performance, but might be worth testing.

I guess there's no way to update the timer without having to write
TCLR to (re)start it?

If the patch helps, then we can clean it up a bit more.
