151cc834f3 pds_vdpa: add support for vdpa and vdpamgmt interfaces 
This is the vDPA device support, where we advertise that we can
support the virtio queues and deal with the configuration work
through the pds_core's adminq.

a16291b5bc pds_vdpa: Add new vDPA driver for AMD/Pensando DSC 
This is the initial auxiliary driver framework for a new vDPA
device driver, an auxiliary_bus client of the pds_core driver.
The pds_core driver supplies the PCI services for the VF device
and for accessing the adminq in the PF device.

This patch adds the very basics of registering for the auxiliary
device and setting up debugfs entries.
