The core driver can now operate in either vmalloc or dma-contig modes;
obviously the latter is preferable when it is supported.  Default is
currently vmalloc on all platforms; load the module with buffer_mode=1 for
contiguous DMA mode.

This is a basic, naive conversion to the videobuf2 infrastructure, removing
a lot of code in the process.  For now, we're using vmalloc, which is
suboptimal, but it does match what the cafe driver did before.  In the cafe
case, it may have to stay that way just because memory is too tight to do
direct streaming; mmp-camera will be able to do better.

This patch adds the VENC or the Video encoder, which is responsible
for the blending of all source planes and timing generation for Video
modes like NTSC, PAL and other digital outputs. the VENC implementation
currently supports COMPOSITE and COMPONENT outputs and NTSC and PAL
resolutions through the analog DACs. The venc block is implemented
as a subdevice, allowing for additional external and internal encoders
of other kind to plug-in.

This patch implements the functionality of the OSD block
of the VPBE. The OSD in total supports 4 planes or Video
sources - 2 mainly RGB and 2 Video. The patch implements general
handling of all the planes, with specific emphasis on the Video
plane capabilities as the Video planes are supported through the
V4L2 driver.

SoC. This patch contains the main implementation of the driver with the
