The UP Squared board comes with different CPUs where Atom ones run at 1.6GHz while the Pentium and Celeron ones run at 1.1GHz. Since the APIC TSC Deadline timer driver is tied to the CPU speed, and we were using 1.6GHz as the hardware clock speed, real world time would not be correct for Pentium and Celeron based boards (i.e. 1 second sleep requested in application does not translate to 1 second in real world). Change it to use HPET timer instead as HPET has the same clock rate for all board variants. Applications requiring more precise clock rate can override this in their configuration.
