This commit implements these two ops in tcpm. To support multiple capabilities, new dt-binding properties need to be defined to create a tree structure for the driver to get each set of capabilities one by one. The first tier of the child node under connector is called "capabilities". Under this child node lies several 2nd tier of child nodes whose names are in the pattern of ^caps[0-9]+$. And the source and sink capabilities are placed in these nodes.
