tests: drivers: i2c: Add test that validates all TWIM instances
Add basic test which checks that all available TWIM instances: - are defined in the board DTS, - are supported by the driver, - can be configured. Test doesn't check parallel operation. Signed-off-by: Sebastian Głąb <[email protected]>
