cxl: Add support for using the kernel API with a real PHB

This hooks up support for using the kernel API with a real PHB. After
the AFU initialisation has completed it calls into the PHB code to pass
it the AFU that will be used by other peer physical functions on the
adapter.

The cxl_pci_to_afu API is extended to work with peer PCI devices,
retrieving the peer AFU from the PHB. This API may also now return an
error if it is called on a PCI device that is not associated with either
a cxl vPHB or a peer PCI device to an AFU, and this error is propagated
down.

cxl: Do not create vPHB if there are no AFU configuration records

The vPHB model of the cxl kernel API is a hierarchy where the AFU is
represented by the vPHB, and it's AFU configuration records are exposed
as functions under that vPHB. If there are no AFU configuration records
we will create a vPHB with nothing under it, which is a waste of
resources and will opt us into EEH handling despite not having anything
special to handle.

This also does not make sense for cards using the peer model of the cxl
kernel API, where the other functions of the device are exposed via
additional peer physical functions rather than AFU configuration
records. This model will also not work with the existing EEH handling in
the cxl driver, as that is designed around the vPHB model.

Skip creating the vPHB for AFUs without any AFU configuration records,
and opt out of EEH handling for them.

cxl: Allow a default context to be associated with an external pci_dev

The cxl kernel API has a concept of a default context associated with
each PCI device under the virtual PHB. The Mellanox CX4 will also use
the cxl kernel API, but it does not use a virtual PHB - rather, the AFU
appears as a physical function as a peer to the networking functions.

In order to allow the kernel API to work with those networking
functions, we will need to associate a default context with them as
well. To this end, refactor the corresponding code to do this in vphb.c
and export it so that it can be called from the PHB code.

Merge branch 'cec-defines' into for-linus

cxl: Make vPHB device node match adapter's

cxl: Make vPHB device node match adapter's

On bare-metal, when a device is attached to the cxl card, lsvpd shows
a location code such as (with cxlflash):
# lsvpd -l sg22
...
*YL U78CB.001.WZS0073-P1-C33-B0-T0-L0
which makes it hard to easily identify the cxl adapter owning the
flash device, since in this example C33 refers to a P8 processor.

lsvpd looks in the parent devices until it finds a location code, so the
device node for the vPHB ends up being used.

By reusing the device node of the adapter for the vPHB, lsvpd shows:
# lsvpd -l sg16
...
*YL U78C9.001.WZS09XA-P1-C7-B1-T0-L3
where C7 is the PCI slot of the cxl adapter.

On powerVM, the vPHB was already using the adapter device node, so
there's no change there.

Tested by cxlflash on bare-metal and powerVM.
