4642269248 dm: vhpet: add vHPET support
vHPET is used as a source of system timer by UEFI (e.g. OVMF).

This provides an alternative to using vPIT, which OVMF assumes is always
connected to vPIC.

This is ported from Bhyve, with a few changes:

- move to user space, using acrn_timer
- enable timers only when necessary
