ath79: suppress GPIO static base allocation warning

Silence ath79 GPIO driver warning by setting GPIO numberspace base
dynamically. This patch also reorganize and fix the GPIO numbers on
6.6 kernel. The new gpio chip base number algorithm:

gpiochip    ath79-SOC    ath9k-0       ath9k-1
base           512      512+ngpios   512+ngpios+10

+Subject: gpio: ath79: convert to dynamic GPIO base allocation
+
+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.
