[media] media: add a VEU MEM2MEM format conversion and scaling driver
Video Engine Unit (VEU) is an IP block, found in multiple SuperH and ARM-
based sh-mobile and r-mobile SoCs, capable of processing video data. It
can perform colour-space conversion, scaling and several filtering
transformations. This patch adds an initial implementation of a mem2mem
V4L2 driver for VEU. So far only conversion from NV12 to RGB565 is
supported. Further functionality shall be added in the future.
This driver is based on a VEU vidix driver by Magnus Damm.
