interconnect: qcom: sa8775p: Add dynamic icc node id support

To facilitate dynamic id allocation, discard the static IDs
from node data and set alloc_dyn_id in descriptor structure
to indicate dynamic ID allocation. Update the topology to use
node pointers for links instead of static IDs and forward declare
the node pointer to avoid undefined references.
