Subject: tracing: Include irqflags headers from trace clock

trace_clock.c includes spinlock.h, which ends up including
asm/system.h, which in turn includes linux/irqflags.h in x86.

So the definition of raw_local_irq_save is luckily covered there,
but this is not the case in parisc:

   tip/kernel/trace/trace_clock.c:86: error: implicit declaration of function 'raw_local_irq_save'
   tip/kernel/trace/trace_clock.c:112: error: implicit declaration of function 'raw_local_irq_restore'

We need to include linux/irqflags.h directly from trace_clock.c
to avoid such build error.
