video: ipuv3: fix framebuffer base address init with multiple IPUs

Browse Source 
Since commit 7812bbdc37 ("video: Correctly handle multiple
framebuffers") the vidconsole output is missing on the primary
display on boards with two IPU units (all i.MX6Q/D based boards).
The base address of the allocated framebuffer is not correctly
programmed in the display controller. Fix it.
