gpio: ath79: convert to dynamic GPIO base allocation

DragonBluep · Bartosz Golaszewski · commit 9a473c2a093e · 2024-06-26T10:39:08.000+02:00
ath79 target has already been converted to device tree based platform. Use dynamic GPIO numberspace base to suppress the warning: gpio gpiochip0: Static allocation of GPIO base is deprecated, use dynamic allocation. Tested on Atheros AR7241 and AR9344.
