[PATCH 4.4.y-cip 6/9] drm: rcar-du: Use the DRM panel API

Biju Das <biju.das.jz@...>

From: Laurent Pinchart <laurent.pinchart+renesas@ideasonboard.com>

commit bf7149f34241dcd6c95ea76b2b5ab4ff33f1c9b9 upstream.

Instead of parsing the panel device tree node manually, use the panel
API to delegate panel handling to a panel driver.

[Removed all other changes except Kconfig. This config is
required for building simple panel driver]
