debugfs.h protects itself from an undefined DEBUG_FS, so it is
not necessary to check it in the driver code or the Makefile.
The driver code had been updated for this, but the Makefile had
missed the update.

These are the adminq commands that will be needed for
setting up and using the vDPA device. There are a number
of commands defined in the FW's API, but by making use of
the FW's virtio BAR we only need a few of these commands
for vDPA support.

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.
