pds_core: set up the VIF definitions and defaults
The Virtual Interfaces (VIFs) supported by the DSC's
configuration (vDPA, Eth, RDMA, etc) are reported in the
dev_ident struct and made visible in debugfs. At this point
only vDPA is supported in this driver so we only setup
devices for that feature.
