test: pinmux: add pincontrol-gpio for pin configuration

Browse Source 
Add a simple pincontrol associated to the sandbox gpio driver,
that allows to check pin configuration with the command pinmux.

The pinmux test is also updated to test behavior with 2 pincontrols.

Example to check LED pin configuration:

=> pinmux list
| Device                        | Driver                        | Parent
| pinctrl-gpio                  | sandbox_pinctrl_gpio          | root_driver
| pinctrl                       | sandbox_pinctrl               | root_driver

=> pinmux dev pinctrl-gpio

=> pinmux status
