Subject: [PATCH] pinctrl: meson: axg: fix gpio_ao bank stop pin

GPIO bank mistakenly stops at GPIOAO_9 while it should stop at GPIOAO_13.
This gives -EINVAL if one tries to set/get anything on GPIOAO_10 to
GPIOAO_13 (pull, direction, value)

Correcting the bank last pin fixes this problem

Fixes: e072b0f1b03a ("pinctrl: meson-axg: Add new pinctrl driver for Meson AXG SoC")

Hi Linus,

This changes fixes code which was added during this cycle, so it intended
for your "for-next" branch, not the "fixes" one.

Thanks
Jerome
