1d27d67ccd Added initial version of the High Precision Event Timer (HPET) ported from Qemu. 
- Created framework based on our I/O APIC code and ported HPET core from Qemu
  with some required changes for the Bochs timer and IRQ handling.
- Enabled HPET-specific code in the ACPI and rombios32 sources and generated
  new ACPI table with iasl.
- The HPET device plugin is now always loaded if the i440FX chipset is selected
  (same as ACPI). We have to rethink this when we have implemented a more
  modern chipset.
- TODO: Rewrite of the virtual timer code for nanosecond support to make the
  realtime synchronization possible with HPET.
