Subject: [PATCH] VFIO: platform: allow the driver to bind to any device explicitly via sysfs

Set match_any_dev and sysfs_bind_only such that echoing a platform
device ID to the driver sysfs bind file will successfully match and bind
the device to the vfio-platform meta-driver in accordance to the
desired semantics for vfio drivers.

Signed-off-by: Kim Phillips <kim.phillips@...aro.org>
