OMAP3: remove OPP interfaces from OMAP PM layer
With new OPP layer, OPP users will access OPP API directly instead of using OMAP PM layer, so remove all notions of OPPs from the OMAP PM layer. Acked-by: Paul Walmsley <paul@pwsan.com> Signed-off-by: Nishanth Menon <nm@ti.com> Signed-off-by: Kevin Hilman <khilman@deeprootsystems.com>
