[PATCH v2] PM/OPP: Set cpu_dev->id in cpumask first

[Pi-Cheng Chen]

Set cpu_dev->id in cpumask first when setting up cpumask for CPUs that
share the same OPP table. This might be helpful when handling cpumask
without the original CPU bitfield set.

v1->v2:
- Set cpu_dev->id in cpumask at the top instead of skip it in the loop
