I looked into moving specific trigger/start/stop logic into the ptimer and it 
really doesn't worth churning the ptimer code, since no other device has similar 
requirements (or they are just incomplete/broken). I'll add one-line patch in V5 
for ptimer_set_limit() to make ptimer_get_count() return correct value for the 
disabled timer, so we won't need the above ad-hoc.
