Thomas Blocher af08f45061 pinctrl: at91: make it work with current gpiolib
[ Upstream commit 752f387faaae0ae2e84d3f496922524785e77d60 ]

pinctrl-at91 currently does not support the gpio-groups devicetree
property and has no pin-range.
Because of this at91 gpios stopped working since patch
commit 2ab73c6d83 ("gpio: Support GPIO controllers without pin-ranges")
This was discussed in the patches
commit fc328a7d1f ("gpio: Revert regression in sysfs-gpio (gpiolib.c)")
commit 56e337f2cf ("Revert "gpio: Revert regression in sysfs-gpio (gpiolib.c)"")

As a workaround manually set pin-range via gpiochip_add_pin_range() until
a) pinctrl-at91 is reworked to support devicetree gpio-groups
b) another solution as mentioned in
commit 56e337f2cf ("Revert "gpio: Revert regression in sysfs-gpio (gpiolib.c)"")
is found
