Add Kconfig entries and pds-vfio-pci.rst. Also, add an entry in the
MAINTAINERS file for this new driver.
It's not clear where documentation for vendor specific VFIO
drivers should live, so just re-use the current amd
ethernet location.

Add the devlink parameter switches so the user can enable
the features supported by the VFs. The only feature supported
at the moment is vDPA.
Example:
devlink dev param set pci/0000:2b:00.0 \
name enable_vnet cmode runtime value true

Add in the support for doing firmware updates. Of the two
main banks available, a and b, this updates the one not in
use and then selects it for the next boot.
Example:
devlink dev flash pci/0000:b2:00.0 \
file pensando/dsc_fw_1.63.0-22.tar

Set up the basic adminq and notifyq queue structures. These are
used mostly by the client drivers for feature configuration.
These are essentially the same adminq and notifyq as in the
ionic driver.
Part of this includes querying for device identity and FW
information, so we can make that available to devlink dev info.
$ devlink dev info pci/0000:b5:00.0
pci/0000:b5:00.0:
driver pds_core
serial_number FLM18420073

Add devlink health reporting on top of our fw watchdog.
Example:
# devlink health show pci/0000:2b:00.0 reporter fw
pci/0000:2b:00.0:
reporter fw
state healthy error 0 recover 0
# devlink health diagnose pci/0000:2b:00.0 reporter fw
Status: healthy State: 1 Generation: 0 Recoveries: 0

This is the initial PCI driver framework for the new pds_core device
driver and its family of devices. This does the very basics of
registering for the new PF PCI device 1dd8:100c, setting up debugfs
entries, and registering with devlink.
