Daniel Leung 5034a77e9e boards: x86/up_squared: use HPET timer
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.
