msm: dcvs: set algo params according to number of online CPUs
It is desirable for performance reasons to be able to run dcvs
with different algorithm parameters depending on the number of
CPUs that are online. The algorithm parameters are already replicated
per-CPU, but all CPUs operate in DCVS with the same parameters at
any given time.
These per-CPU parameters now correspond to the total number of CPUs
online. For example, if 2 CPUs are online, the algorithm parameters
for CPU2 are used.
