gpiolib: of: allow of_gpiochip_find_and_xlate to find more than one chip per node

The change:

7b8792bbdffdff3abda704f89c6a45ea97afdc62
gpiolib: of: Correct error handling in of_get_named_gpiod_flags

assumed that only one gpio-chip is registred per of-node.
Some drivers register more than one chip per of-node, so
adjust the matching function of_gpiochip_find_and_xlate to
not stop looking for chips if a node-match is found and
the translation fails.
