Migrate i8253 driver to the new 'set-state' interface provided by clockevents core, the earlier 'set-mode' interface is marked obsolete now. This also enables us to implement callbacks for new states of clockevent devices, for example: ONESHOT_STOPPED.

There are multiple declarations of global_clock_event in header files specific to particular clock event implementations. Consolidate them in <asm/time.h> and make sure all users include that header.

Move them to drivers/clocksource/i8253.c and remove the implementations in arch/ [ tglx: Avoid the extra file in lib - folded arch patches in.

i8253_lock needs to be a real spinlock in preempt-rt, i.e. it can not be converted to a sleeping lock. Convert it to raw_spinlock and fix up all users.
