When building gpio timed keys driver as a LKM, we hit an error:
FATAL: modpost: GPL-incompatible module gpio_timed_keys.ko uses GPL-only symbol 'platform_driver_unregister'

This is because we have a typo in MODULE_LICENSE which makes
kernel thinks it's a proprietary module.

Create gpio_timed_keys driver that detects timed key
presses and allows input devices to send different
key codes based on the amount of time the key was
pressed.
