Unless using multiple named properties is really preferred over a single
"gpios" property I would like to keep the single property containing
a list of GPIOs. Each list entry has clearly defined meaning and it
seems simpler to me to reference the GPIOs by index, rather than by name.
This also saves a few bytes in dtb and there is no need to store the list
of names in the driver.

Thanks,
Sylwester
