linuxkpi: Include <linux/spinlock.h> from <linux/refcount.h>

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.

linuxkpi: refcount: Use atomic_t directly

Simply use a typedef for refcount_t on atomic_t, this allow us
to use a nativ type and also changing struct kref to directly use
a refcount_t like Linux.
