ARM: kernel: provide cluster to logical cpu mask mapping API

Some device drivers like PMU require to retrieve the logical cpu mask
that corresponds to a given cluster id. This patch provides a hook in
the topology code that, given an existing cluster id as input,
initializes the corresponding cpumask passed as a pointer, reusing all
existing topology information required by sched domains in the kernel.
