[PATCH v7 16/17] drm: rcar-du: Move rcar_du_properties_init()

[Biju Das]

Move rcar_du_properties_init() to RCar DU kms lib, so that it can be
shared by both RCar and RZ/G2L kms drivers.

Signed-off-by: Biju Das <biju.das.jz@xxxxxxxxxxxxxx>

v6->v7:
 * Rebased to drm-tip.
v1->v6:
 * Rebased on drm-misc-next and DU-next.
v1:
 * Created the lib suggested by Laurent.
