[PATCH 2/3] drm: rcar-du: add model field to struct rcar_du_device_info

[Sergei Shtylyov <sergei.shtylyov@xxxxxxxxxxxxxxxxxx>]

In order to add the R-Car V3M (R8A77970) support to the DU driver we'd need
to keep  track  not only  of the SoC generation but also of the exact model
(for the LVDS encoder support).  Therefore add the 'model'  field  to the
'struct rcar_du_device_info' and initialize it accordingly  for the already
supported SoCs.
