[PATCH V3 2/6] PM / OPP: Rename opp init/free table routines

[PATCH V3 2/6] PM / OPP: Rename opp init/free table routines

[Viresh Kumar]

free-table routines are opposite of init-table ones, and must be named
to make that clear. Opposite of 'init' is 'exit', but those doesn't suit
really well.

Replace 'init' with 'add' and 'free' with 'remove'.

[PATCH V3 3/6] PM / OPP: Prefix exported opp routines with dev_pm_opp_

[Viresh Kumar]

That's the naming convention followed in most of opp core, but few
routines didn't follow this, fix them.
