Krzysztof Opasiak fdc01cc286 usb: gadget: printer: Remove pnp_string static buffer
pnp string is usually much shorter than 1k so let's stop wasting 1k of
memory for its buffer and make it dynamically alocated.
This also removes 1k len limitation for pnp_string and
adds a new line after string content if required.
