[PATCH v2] pinctrl: aspeed: Use managed pinctrl registration

[Prasanth Kumar Padarthi <prasanth.padarthi10@gmail.com>]

The shared Aspeed probe helper registers its controller with
pinctrl_register(), but does not unregister it on device unbind.
The registration can therefore outlive device-managed data.

Use devm_pinctrl_register() to ensure the controller is unregistered
during device teardown.
