ASoC: sun4i-codec: add h616 card long_name

Adding jack detection requires sound servers to act on the emitted
events, which are described by ALSA Use Case Manager configurations in
userspace. These configurations include the long card name in the file
path (falling back to card->name if this is not present), so add a long
card name for the H616 without spaces, making UCM referencing easier.

The corresponding ALSA UCM patch is here (now merged):
