selftest/gpio: add gpio test case This test script try to do whitebox testing for gpio subsystem(based on gpiolib). It manipulate gpio device through chardev or sysfs and check the result from debugfs. This script test gpio-mockup through chardev by default. User could test other gpio chip by passing the module name. Some of the testcases are turned off by default to avoid the conflicting with gpiochip in system. In details, it test the following things: 1. Test direction and output value for valid pin. 2. Test dynamic allocation of gpio base. 3. Add single, multi gpiochip to do overlap check. Run "tools/testing/selftests/gpio/gpio-mockup.sh -h" for usage.
