refactor(msm8916): handle multiple CPU clusters
Some Qualcomm platforms similar to MSM8916 have multiple CPU clusters.
In this case, some of the hardware blocks are duplicated and must be
configured separately.
Refactor the code to handle additional clusters by introducing loops
and some conditionals.
No functional change for existing single cluster platforms.
