drm: rcar-du: Link CRTCs to the DU device
The rcar_du_crtc functions have a heavy reliance on the rcar_du_group
structure, in many cases just to access the DU device context.
To better separate the groups out of the CRTC handling code, give the
rcar_du_crtc its own pointer to the device and remove the indirection
through the group pointers.
