[PATCH v2 1/4] OMAP OPP: Add accessor function for getting OPP ID.

[Kevin Hilman <khilman@deeprootsystems.com>]

Add new function opp_get_opp_id() for finding the OPP ID of a given
OPP.  This allows us to further hide OPP layer details.

NOTE: OPP IDs are deprecated, and this function will eventually
      be removed after all users of OPP IDs are removed.
