[PATCH v7 00/17] Add RCar DU lib support

[Biju Das]

The DU controller on RZ/G2L LCDC is similar to R-Car as it is
connected to VSPD. RCar DU lib is created for sharing kms, vsp and encoder
driver code between both RCar and RZ/G2L alike SoCs.

Tested this patch series on RZ/{G2M, G2L, G2LC} and RZ/V2L platforms.

v6->v7:
 * Split DU lib and  RZ/G2L du driver as separate patch series as
   DU support added to more platforms based on RZ/G2L alike SoCs.
 * Rebased to latest drm-tip.
v5->v6:
 * Merged DU lib and RZ/G2L du driver in same patch series
 * Rebased to latest drm-misc.
 * Merged patch#1 to RZ/G2L Driver patch.
 * Updated KConfig dependency from ARCH_RENESAS->ARCH_RZG2L.
 * Optimized rzg2l_du_output_name() by removing unsupported outputs.

v4->v5:
 * Added Rb tag from Rob for binding patch.
 * Started using RCar DU libs(kms, vsp and encoder)
 * Started using rcar_du_device, rcar_du_write, rcar_du_crtc,
   rcar_du_format_info and rcar_du_encoder.
v3->v4:
 * Changed compatible name from renesas,du-r9a07g044->renesas,r9a07g044-du
 * started using same compatible for RZ/G2{L,LC}
 * Removed rzg2l_du_group.h and struct rzg2l_du_group
 * Renamed __rzg2l_du_group_start_stop->rzg2l_du_start_stop
 * Removed rzg2l_du_group_restart
 * Updated rzg2l_du_crtc_set_display_timing
 * Removed mode_valid callback.
 * Updated rzg2l_du_crtc_create() parameters
 * Updated compatible
 * Removed RZG2L_DU_MAX_GROUPS
V2->v3:
 * Added new bindings for RZ/G2L DU
 * Removed indirection and created new DRM driver based on R-Car DU
v1->v2:
 * Based on [1], all references to 'rzg2l_lcdc' replaced with 'rzg2l_du'
 * Updated commit description for bindings
 * Removed LCDC references from bindings
 * Changed clock name from du.0->aclk from bindings
 * Changed reset name from du.0->du from bindings
 * Replaced crtc_helper_funcs->rcar_crtc_helper_funcs
 * Updated macro DRM_RZG2L_LCDC->DRM_RZG2L_DU
 * Replaced rzg2l-lcdc-drm->rzg2l-du-drm
 * Added forward declaration for struct reset_control

RFC->v1:
 * Changed  minItems->maxItems for renesas,vsps.
 * Added RZ/G2L LCDC driver with special handling for CRTC reusing
   most of RCar DU code
 * Fixed the comments for num_rpf from rpf's->RPFs/ and vsp->VSP.
