* [PATCH] v4l2-compliance: split node at testNode() in two nodes

v4l2-compliance tests deals with memory-to-memory devices (m2m) like
they are a single device, through the struct node. This is indeed the
most usual case. However, there are m2m devices that have two
separated devices for the capture queue and for the output queue, and
the current design does not support they.

Split the node on testNode and related functions in two arguments:
struct node node and struct node node_m2m_cap. For now, use the same node in
both arguments.

Hello,

This is an effort to support topologies with video loopback (i.e. an
output device and a capture in the same media path). A future patch will
add a new option (--output) to specify the output device to be used with
the --device to form the loopback. With that option, the arguments node
and node_m2m_cap would not be the same device, as in this patch.
I may forgot to replace in some function, please notify my if you find
something missing.

Thanks,
	André
