drm: rcar-du: Add r8a7742 support

Browse Source 
Add direct support for the r8a7742 (RZ/G1H).

The RZ/G1H shares a common, compatible configuration with the r8a7790
(R-Car H2) so that device info structure is reused, the only difference
being TCON is unsupported on RZ/G1H (Currently unsupported by the driver).
