video-driver: prepare conflict free dependency list

Browse Source 
Convert multi-parent, multi-child based dependency tree
into flattened list. It is organized in such a way that
all parents willbe present before self or any child node.

For some caps, adjust sequence is called without preparing
parent nodes. So that is leading to undefined behaviour.

Added change to address these problems.
