msm: dcvs_idle: Provide CPU core idle information to msm_dcvs

The msm_dcvs algorithm takes in core idle information and outputs the
frequency for the core to run at. This driver registers with the
CPU_PM interface to get the idle enter and idle exit notification and
passes this to the msm_dcvs driver for every CPU core.
