tests/drivers/gpio_basic_api: improve support for pull test

Browse source 
The pull test assumed it was possible to configure the GPIO to be
disconnected.  Some peripherals don't support a disconnected GPIO pin,
so if disconnected is not supported emit a note and attempt to
configure the output pin as an input.
