[ARM] dyntick: Remove obsolete and unused ARM dyntick support

dyntick is superseded by the clocksource/clockevent infrastructure,
using the NO_HZ configuration option.  No one implements dyntick on
ARM anymore, so it's pointless keeping it around.  Remove dyntick
support.

-        help
-          Select this option if you want to disable continuous timer ticks
-          and have them programmed to occur as required. This option saves
-          power as the system can remain in idle state for longer.
-
-          By default dynamic tick is disabled during the boot, and can be
-          manually enabled with:
-
-            echo 1 > /sys/devices/system/timer/timer0/dyn_tick
-
-          Alternatively, if you want dynamic tick automatically enabled
-          during boot, pass "dyntick=enable" via the kernel command string.

-          Please note that dynamic tick may affect the accuracy of
-          timekeeping on some platforms depending on the implementation.
-          Currently at least OMAP, PXA2xx and SA11x0 platforms are known
-          to have accurate timekeeping with dynamic tick.
