Subject: [PATCH] gpio: aspeed: fix the GPIO number passed to pinctrl_gpio_set_config()

From: Bartosz Golaszewski <bartosz.golaszewski@...aro.org>

pinctrl_gpio_set_config() expects the GPIO number from the global GPIO
numberspace, not the controller-relative offset, which needs to be added
to the chip base.

Fixes: 5ae4cb94b313 ("gpio: aspeed: Add debounce support")
