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.

This patch adds V4L2 driver for Samsung S3C24XX/S3C64XX SoC series
camera interface. The driver exposes a subdev device node for CAMIF
pixel resolution and crop control and two video capture nodes - for
the "codec" and "preview" data paths. It has been tested on Mini2440
(s3c2440) and Mini6410 (s3c6410) board with gstreamer and mplayer.

This uses the ARCH_MXC specific iram_alloc API to allocate a work
buffer in the SoC's on-chip SRAM and sets up the AXI_SRAM_USE
register. In the future, the allocation will be converted to use
the genalloc API.

-EMISSINGMAKEFILE
Without a Makefile, the driver will not compile, causing
breakages for arm exynos5 sub-architecture.

Instead of having 3 options to allow customizing the media
sub-drivers (tuners, I2C drivers, frontends), merge all of
them into just one.
That simplifies the life for users, as they can just keep
this untouched.
Life for developers is also simpler, as there's now just
one Kconfig item to remember, for the ancillary sub-drivers
providing supports for chips that could change from one
board design to another.

- get rid of ridden V4L2_COMMON symbol
This symbol is not needed anymore; it can be folded with V4L2
one, simplifying the Kconfig a little bit;
- Comment why some Kconfig items are needed;
- Remove if test for MEDIA_CAMERA_SUPPORT, replacing it by
depends on.

Vivi is not that important to appear at the main menu, so move it
to its own submenu. Also, the mem2mem test device driver is
similar to vivi. So, put both at the same menu.

That helps to better organize the soc_camera items.
While here, cleanup Makefiles, removing uneeded include dirs.

The remaining drivers are mostly platform drivers. Name the
dir to reflect it.
It makes sense to latter break it into a few other dirs.
