Subject: pinctrl: meson: Drop pinctrl_unregister for devm_ registered device

From: Wei Yongjun <[email protected]>

commit 5b236d0fde21d88351420ef0b9a6cb7aeeea0c54 upstream.

It's not necessary to unregister pin controller device registered with devm_pinctrl_register() and using pinctrl_unregister() leads to a double free.

This is detected by Coccinelle semantic patch.
