tests: drivers: gpio: gpio_basic_api: Add support for kv260

Add gpio driver testcase support for kv260. The overlay will select the
PS gpio bank to be tested.
Add test scenario name with filter and etra_arg for kv260.

For running this testcase on kv260 PS gpio bank 3 has been chosen
because it is EMIO and design is required to connect pins together.
