tick: Document TICK_ONESHOT config option

Browse source 
This option has been selected from arch code as it was assumed that
it's necessary to support oneshot mode clockevent devices. But it's
just a core internal helper to compile tick-oneshot.c if NOHZ or
HIG_RES_TIMERS are selected.

# Timer subsystem related configuration options

# Core internal switch. Selected by NO_HZ / HIGH_RES_TIMERS. This is
# only related to the tick functionality. Oneshot clockevent devices
