Currently GPIO controllers can only be referred to by label in GPIO
lookup tables.

Add support for looking them up by "gpiochipN" name, with "N" either the
corresponding GPIO device's ID number, or the GPIO controller's first
GPIO number.

What the commit message is missing is a rationale, why is this needed?

Right. To be added: so they can be looked up in the GPIO lookup table
using either the chip's label, or the "gpiochipN" name.

After reading the aggregator/forwarder driver I am not convinced
that this is needed at all and I think this patch can be dropped,
but check my review and see what you think!

Thanks,
