Add the first API functions that directly deal with node dependency
ordinals as determined by edtlib:
- DT_DEP_ORD(node_id): node_id's ordinal
- DT_REQUIRES_DEP_ORDS(node_id): list of dep ordinals for node_id's
direct dependencies
- DT_SUPPORTS_DEP_ORDS(node_id): list of dep ordinals for nodes
depending directly on node_id
- DT_INST_ equivalents
This is not meant to be an exhaustive set of macros related to
dependency ordinals; rather, it's a starting out point meant to enable
initial struct device dependency tracking work. We can add more if
needed.
