When none of CONFIG_PM_OPP or CONFIG_OF is enabled we use the dummy implementation of of_init_opp_table() routine, which returns -EINVAL currently. -EINVAL can confuse the callers a bit as it can have other meanings for the actual implementation of this routine.
It is more appropriate to return -ENOSYS instead to avoid confusion at caller.
