gpio: aggregator: Return an error if there are no GPIOs in gpio_aggregator_parse()

Browse Source 
The error handling in gpio_aggregator_parse() was re-written.  It now
returns success if there are no GPIOs.  Restore the previous behavior
and return -EINVAL instead.

Fixes: 83c8e3df64 ("gpio: aggregator: expose aggregator created via legacy sysfs to configfs")
