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.
