goodixmoc: support for clear_storage

Browse Source 
The internal storage of this device can get messed up by other operating
systems, so it's handy to be able to clear it.

I'm not 100% sure whether the commands I've sent to the device are
exactly what is supposed to be used (just a guess), but it did seem to
work, and it even fixed another issue I had.
