m68k: hardirq_count() only need preempt_mask.h

Browse Source 
The m68k irqflags implementation needs to check hardirq
context in some cases.

As it is a very low level header file, it's better to
include preempt_mask.h rather than hardirq.h when the
only purpose is to use irq context APIs. This way we
can avoid future header circular dependencies when
vtime.h will expand to use static keys.
