amd64: lapic: refactor timer programming
We reprogram the lapic timer by hand in three separate places.
This is error-prone and difficult to read.
To clean things up, introduce routines for reprogramming the lapic
timer in a given mode. lapic_timer_oneshot() starts a oneshot
countdown. lapic_timer_periodic() starts a repeating countdown.
Both of these routines call lapic_timer_start(), wherein we actually
write the lapic registers.
With input from dlg@.
Earlier version eyeballed by mlarkin@.
Suspend/resume tested by gnezdo@.
