[PATCH v3 1/3] pinctrl: pinctrl-oxnas: remove obsolete pinctrl driver

From: Neil Armstrong
Date: Mon Aug 14 2023 - 04:17:41 EST

Due to lack of maintenance and stall of development for a few years now,
and since no new features will ever be added upstream, remove support
for OX810 and OX820 pinctrl & gpio.
