Subject: pinctrl: meson: fix gpio request disabling other modes

From: Neil Armstrong <narmstrong@baylibre.com>

commit f24d311f92b516a8aadef5056424ccabb4068e7b upstream.

The pinctrl_gpio_request is called with the "full" gpio number, already
containing the base, then meson_pmx_request_gpio is then called with the
final pin number.
Remove the base addition when calling meson_pmx_disable_other_groups.

Fixes: 6ac730951104 ("pinctrl: add driver for Amlogic Meson SoCs")
