APB timer is the replacement for 8254, HPET on X86 MID platforms.
The APBT provides a stable time base on SMP
systems, unlike the TSC, but it is more expensive to access,
as it is off-chip. APB timers are always running regardless of CPU
C states, they are used as per CPU clockevent device when possible.
