tools: gpio: remove uAPI v1 code no longer used by selftests

gpio-mockup-chardev helper has been obsoleted and removed, so also remove
the tools/gpio code that it, and nothing else, was using.

- *                     such as "gpiochip0"
- * @lines:             An array desired lines, specified by offset
- *                     index for the associated GPIO device.
- * @num_lines:         The number of lines to request.
- * @flag:              The new flag for requsted gpio. Reference
- *                     "linux/gpio.h" for the meaning of flag.
- * @data:              Default value will be set to gpio when flag is
- *                     GPIOHANDLE_REQUEST_OUTPUT.
- * @consumer_label:    The name of consumer, such as "sysfs",
- *                     "powerkey". This is useful for other users to
- *                     know who is using.
- *
- * Request gpio lines through the ioctl provided by chardev. User
- * could call gpiotools_set_values() and gpiotools_get_values() to
- * read and write respectively through the returned fd. Call
- * gpiotools_release_linehandle() to release these lines after that.
- *
- * Return:             On success return the fd;
- *                     On failure return the errno.
