Subject: [PATCH] pinctrl: meson: fix gpio request disabling other modes

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")
