User controlled data needs to be validated before
processing, otherwise it may corrupt existing data
and other programming variables which may further
lead to crash in kernel space.
This change validates user specified buffer's data,
such as offset and data length, before performing
any operations in kernel.

This change will remove the kernel mapping of input and
output buffers for both video encoder and decoder to
avoid the errors resulting from ion_map_kernel() for
high resolution video concurrency use cases due to the
limited vmalloc space. It also removed the metadata
processing in kerner video driver as kernel virtual
address is removed. The metadata processing can be
done in user space video component.

There can be SoCs which have different amount of VFEs connected to
ISPIF, while the CSID version is kept the same. For such cases there is
a need to have additional information about the number of VFEs connected
to each ISPIF interface, and its capabilities.
As there is no way for the ISPIF to guess this information on its own,
this change introduces a new ISPIF ioctl cmd, called ISPIF_SET_VFE_INFO.
This command will store the information for the number of VFEs connected
and also VFEs capabilities.
The above information is used where number of VFEs information is
required. Such places are vfe clock request, ISPIF irq handling and
others.

For concurrent ISP operation, a single camera image is
split and feed into two ISP. Each ISP will process
the image independently and output to different location in
one single buffer. This change add support to synchronize
the buffer used in each ISP. When the first ISP dequeue
a buffer, the buffer will be store in a separate queue.
The second ISP will first check the intermediate queue
and then check the main queue for buffer. When ISP is done
processing the image, the buffer will be send out only
when both ISPs are done with the buffer.
