d9d87d90cc treewide: rename GPIO set callbacks back to their original names
The conversion of all GPIO drivers to using the .set_rv() and
.set_multiple_rv() callbacks from struct gpio_chip (which - unlike their
predecessors - return an integer and allow the controller drivers to
indicate failures to users) is now complete and the legacy ones have
been removed. Rename the new callbacks back to their original names in
one sweeping change.

d68ddf651d gpio: rtd: use new GPIO line value setter callbacks
struct gpio_chip now has callbacks for setting line values that return
an integer, allowing to indicate failures. Convert the driver to using
them.

c8fb5a52b9 gpio: rtd: Fix signedness bug in probe
The "data->irqs[]" array holds unsigned int so this error handling will
not work correctly.
