Qemu implements HPET so that it is connected to IRQ 2, which makes necessary to use it in legacy emulation mode. Add legacy emulation mode to HPET driver. Change the way the HPET driver is initialized. QEMU requires that the mode (one shot or periodic) gets set prior loading comparator value. Add debugging mode to HPET driver to ease the next port.
