  pci: Allow PCI bus subtypes to support extended config space accesses

Some PHB implementations, eg. PAPR used on pseries machine, act like
a regular PCI bus rather than a PCIe bus, but allow access to the
PCIe extended config space anyway.

Introduce a new PCI bus class method to modelize this behaviour and
use it when adjusting the config space size limit during accesses.

No behaviour change for existing PCI bus types.

  -----------
  spapr_pci: Fix extended config space accesses

The PAPR PHB acts as a legacy PCI bus but it allows PCIe extended
config space accesses anyway (for pseries-2.9 and newer machine
types).

Introduce a specific PCI bus subtype to inform the common PCI code
about that.

This is a small, hard freeze, pull request which fixes a regression on
the pseries machine handling of PCI-E extended config space accesses.
