Needed by platform device drivers, such as the vfio-platform driver
later in series, in order to bypass the existing OF, ACPI, id_table and
name string matches, and successfully be able to be bound to any
device, like so:
echo vfio-platform > /sys/bus/platform/devices/fff51000.ethernet/driver_override
echo fff51000.ethernet >
/sys/bus/platform/devices/fff51000.ethernet/driver/unbind
echo fff51000.ethernet > /sys/bus/platform/drivers_probe
This mimics "PCI: Introduce new device binding path using
pci_dev.driver_override" [1], which is an interface enhancement
for more deterministic PCI device binding, e.g., when in the
presence of hotplug.

Looks largely identical to the PCI version of the same that has been
accepted for v3.16 and ack'd by GregKH.

Yup, would be great to have feature parity for device binding on
platform and PCI.
