pds_core: add support for identity version 2
Add a new capabilities field in struct pds_core_dev_identity,
which requires bumping the identity version to 2, i.e.
PDS_CORE_IDENTITY_VERSION_2. If version 2 negotiation fails,
then quietly fall back to version 1. If version 1 negotiation
fails, then driver load will fail.
Another patch in the series will make use of the capabilities
field.
