drm/panel: sofef00: Introduce compatible which includes the panel name

Compatible should correspond to the panel used and the driver currently
supports only AMS628NW01 panel. Adapt the internal driver structures to
reflect the name.
Original, not very descriptive, compatible is kept to ensure compatibility
with older device-trees.
