. Removing the devices will do nothing
since it's not populated, and we'll set the power state of the slot
back to off.

cond part is modifications to the PCI hotplug driver on powernv,
so that a virtual slot is created for the opencapi adapters found in
the device tree.

powerpc/powernv/ioda:
Protect the PHB's list of PE. Probably not needed as long as it was
populated during PHB creation, but it feels right and will become
required once we can add/remove opencapi devices on hotplug.

Also separate the undo of the PELT-V code in a separate function, it
is not needed for NPU devices and it improves a bit the readability of
the code.

of the reconfiguration of the bridge, but for opencapi
PHBs, we don't have an intermediate bridge. So let's define the PE
when the device is enabled. PEs are meaningless for opencapi, the NPU
doesn't define them and opal is not doing anything with them.

comment (removed here as no longer needed) was stating as much.
