[PATCH 2/3] ppc/pnv: Fixes for user-created pnv-phb5 devices

[Frederic Barrat <fbarrat@linux.ibm.com>]

Two small fixes to fix user-created devices for POWER10:
- always create the PECs (PCI Express Controller) for the system. The
PECs host the PHBs and we try to find the matching PEC when creating a
PHB, so it must exist. It also matches what we do on POWER9
- the machine class must allow dynamically allocated system bus

Fixes: 623575e16cd5 ("ppc/pnv: Add model for POWER10 PHB5 PCIe Host bridge")
