[PATCH v4 3/3] OMAP3: remove OPP interfaces from OMAP PM layer

[nm@ti.com (Nishanth Menon)]

From: Kevin Hilman <khilman@deeprootsystems.com>

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>

v4: identical to v3 with Acked-by added
posted for completeness sake - no change involved
v3: no longer explicitly calling the init_table, instead
    depending on the device_initcall to initialize as needed

v2: https://patchwork.kernel.org/patch/266931/
