Add a new kselftest that sets a configuration to a GPIO line and then gets it back to verify that it was correctly carried out by the driver.

Setting a configuration is done through the GPIO uAPI, but retrieving it is done through the debugfs interface since that is the only place where it can be retrieved from userspace.

The test reads the test plan from a YAML file, which includes the chips and pin settings to set and validate.

Bartosz needs to review this too.

It also looks good though, thanks for expanding the tests!
