[Skiboot] [PATCH] npu2-opencapi: Fix assert on link reset during init

[Frederic Barrat]

We don't support resetting an opencapi link yet.

Commit fe6d86b9 ("pci: Make fast reboot creset PHBs in parallel")
tries resetting any PHB whose slot defines a 'run_sm' callback. It
raises an assert when applied to an opencapi PHB, as 'run_sm' calls
the 'freset' callback, which is not yet defined for opencapi.

Fix it for now by removing the currently useless definition of
'run_sm' on the opencapi slot. It will print a message in the skiboot
log because the PHB cannot be reset, which is correct. It will all go
away when we add support for resetting an opencapi link.
