lima/ppir: add node dependency types

Currently we add dependecies in 3 cases:
1) One node consumes value produced by another node
2) Sequency dependencies
3) Write after read dependencies

2) and 3) only affect scheduler decisions since we still can use pipeline
register if we have only 1 dependency of type 1).

Add 3 dependency types and mark dependencies as we add them.
