    linuxkpi: Include <linux/spinlock.h> from <linux/refcount.h>
    
    The <linux/refcount.h> header uses the `spinlock_t` type and some
    consumers in the DRM drivers don't include <linux/spinlock.h> directly
    or indirectly. This led to compilation errors because the type was
    undefined.
    
    On Linux, <linux/refcount.h> includes <linux/spinlock_type.h> as a
    comparision.
