Switch the driver from legacy gpio API that is deprecated to the newer
gpiod API that respects line polarities described in ACPI/DT.

The driver still tries to support shared reset lines, by first trying to
allocate the reset GPIO normally, and then non-exclusively, although the
utility of such support is questionable, toggling reset line from one
driver/instance will result in all chips being reset, potentially at an
inopportune moment.

Note that this change depends on commit fbbbcd17 ("gpiolib: of: add
quirk for locating reset lines with legacy bindings") to translate
request for "reset" GPIO to the legacy name "gpio-reset" in case when
proper name is not used.
