[PATCH] ppc/pnv: Remove the XICSFabric Interface from the POWER9 machine

[Cédric Le Goater]

The POWER8 PowerNV machine needs to implement a XICSFabric interface
as this is the POWER8 interrupt controller model. But the POWER9
machine uselessly inherits of XICSFabric from the common PowerNV
machine definition.

Open code machine definitions to have a better control on the
different interfaces each machine should define.

Fixes: f30c843ced50 ("ppc/pnv: Introduce PowerNV machines with fixed CPU 
models")
