[PATCH v5 3/4] gpiolib: Pass array info to get/set array functions

[Janusz Krzysztofik <jmkrzyszt@gmail.com>]

In order to make use of array info obtained from gpiod_get_array() and
speed up processing of arrays matching single GPIO chip layout, that
information must be passed to get/set array functions.  Extend the
functions' API with that additional parameter and update all users.
Pass NULL if a user bulids an array itself from single GPIOs.
