RZ/G2L LCD controller composed of Frame compression Processor(FCPVD),
Video signal processor (VSPD) and Display unit(DU). The output of LCDC is
connected to Display parallel interface and MIPI link video interface.

This patch series aims to add basic display support on RZ/G2L SMARC EVK
platform. The output from DSI is connected to ADV7535.

The DU controller is similar to R-Car as it is connected to VSPD,
so most of code is based on R-Car with new CRTC/DRM driver specific to
RZ/G2L

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.
