timer: tickless: hpet: Add tickless kernel support
Update the timer to use the tickless kernel interface
provided by kernel to operate in event based mode. In
this mode, the timer would not generate periodic ticks
and would only be programmed in one shot mode. It would
announce elapsed time in wall time units instead of
ticks. Timer can also be disabled enabling waiting
forever for a non-timer event.
