pinctrl: meson: amlogic-a4: mark the GPIO controller as sleeping
[ Upstream commit d6df4abe95a409e812c5d9af9657fe63ac299e3a ]
The GPIO controller is configured as non-sleeping but it uses generic
pinctrl helpers which use a mutex for synchronization. This will cause
lockdep splats when used together with shared GPIOs going through the
GPIO shared proxy driver.
Fixes: 6e9be3abb78c ("pinctrl: Add driver support for Amlogic SoCs")
