bit_spinlock: Include missing <asm/processor.h>
Including <linux/bit_spinlock.h> into an empty TU will result in the
compiler complaining:
./include/linux/bit_spinlock.h:34:4: error: call to undeclared function 'cpu_relax'; <...>
34 | cpu_relax();
| ^
1 error generated.
Include <asm/processor.h> to allow including bit_spinlock.h where
<asm/processor.h> is not otherwise included.
