Since its inclusion in v3.9, no users of the SuperH VEU mem2mem video
processing driver have appeared upstream. All VEU devices in SuperH
board code still bind to the "uio_pdrv_genirq" driver instead.
The original author marked the driver orphaned in v3.15.
Remove the driver; it can always be resurrected from git history when
needed.
