Wu Zhou 64d999e703 hv: switch to dynamic timer in bvt scheduler ...

When bvt scheduler picks up a thread to run, it sets up a counter
‘run_countdown’ to determine how many ticks it should remain running.
Then the timer will decrease run_countdown by 1 on every 1000Hz tick
interrupt, until it reaches 0. The tick interrupt consumes a lot of
power during idle (if we are using HLT in idle thread).

This patch is to switch the 1000 HZ timer to a dynamic one, which only
interrupt on run_countdown expires.
