Integrate HPET so the functions used for getting time can have a higher accuracy
Integrate HPET so host_get_time, host_get_time64, and host_get_uptime64
are more precise. The highest precision can be 10ns when this patch is
applied.
* i386/i386/apic.c: Implement the two high-precision clock interface functions
added in this patch for i386.
* i386/i386at/model_dep.c: Initialize HPET if APIC is defined
* kern/mach_clock.c: Integrate the high-precision clocks to have the
10ns precise time values.
* kern/mach_clock.h: Add two new interface functions for accessing the
high-precision clocks.
