drm: rcar-du: Fix vblank initialization
[ Upstream commit 3d61fe5f59dd3e6f96fc0772156d257cb04dc656 ]
The drm_vblank_init() takes the total number of CRTCs as an argument,
but the rcar-du driver passes a bitmask of the CRTC indices. Fix it.
Fixes: 4bf8e1962f91 ("drm: Renesas R-Car Display Unit DRM driver")
