    LinuxKPI: add supporting #includes
    
    Compiling drm-kmod on !X86 does not include asm/smp.h which includes
    preempt.h on FreeBSD.  In order to compile drm-kmod on other
    architectures add the secondary #includes for preempt.h to
    spinlock.h and hardirq.h (which now also gets included from highmem.h)
    to connect the #include chain.
