score: Add and use ISR locks

ISR locks are low-level locks to protect critical sections accessed by
threads and interrupt service routines.

On single processor configurations the ISR locks degrade to simple ISR
disable/enable sequences. No additional storage or objects are
required.

This synchronization primitive is supported on SMP configurations. Here
SMP locks are used.
