[PATCH 0/3] PCI: arm64/powerpc: Fix parsing of linux,pci-probe-only

[Marc Zyngier <marc.zyngier@arm.com>]

The pci-host-generic driver parses the linux,pci-probe-only property,
and assumes that it will have a boolean parameter.

Turns out that the Seattle DTS file has a naked "linux,pci-probe-only"
property, which leads to the driver dereferencing some unsuspecting
memory location. Nothing really bad happens (we end up reading some
other bit of DT, fortunately), but that not a reason to keep it this
way.

The first patch fixes the driver not to do silly things, and simply
give a warning when this happens. The powerpc code from where this
code was lifted is also fixed in a second patch.

Finally, the bad property is removed from the Seatle DTS, because it
is simply not necessary (it actually prevents me from using SR-IOV,
which otherwise runs fine without the probe-only thing).
