msm: dcvs: create cpu freq table dynamically

CPU frequencies can differ between different revisions, so create
the table of cpu frequencies dynamically based on data from
acpuclock rather than using a fixed table.

Some of the data in the table comes from sync points that will be
implemented between CPU and GPU frequencies. The sync points are
defined here, but the sync implementation itself will come in a
subsequent commit.
