[PATCH V2 1/7] opp: remove -ENOSYS from dummy implementation of of_init_opp_table()

When any of CONFIG_PM_OPP or CONFIG_OF isn't enabled we have a dummy
implementation of of_init_opp_table() routine, it returns -EINVAL currently.
-EINVAL can be returned from other places within the real implementations of
of_init_opp_table() and so caller wouldn't be able to differentiate between
those two cases.

Make it return -ENOSYS instead for better handling.
