Both RZ/G2L and RCar display system uses similar hardware pipeline for
display ie, it uses FCPV, VSPD and DU. Both FCPV and VSPD are almost
similar, but DU there are some differences like it does not have
plane/group registers.

Since the pipeline and software architecture are similar, we can reuse the
DU code for RCar to RZ/G2L as well.

This patch series adds RCar DU lib support(Encoder, vsp and KMS) by moving
common codes with some trivial changes to the lib.

The subsequent patch series will add support for RZ/G2L DU.

Note:
 * This patch series is based on drm-misc-next and du-next
 * The KConfig and Make file depend upon [1]
[1] https://patchwork.kernel.org/project/linux-renesas-soc/patch/20220829091901.641784-3-biju.das.jz@bp.renesas.com/

v1->v2:
 * Rebased on drm-misc-next and DU-next.
 * Fixed the warning reported by bot for patch#2.
