Subject: [PATCH 1/3] driver core: faux: Suppress bind attributes

faux_device_create() is almost a suitable candidate to replace
platform_driver_probe() if not for the fact that faux_device_create()
supports dynamic attach/detach of the driver.

Drop the bind attributes with the expectation that simple faux devices can
always assume that the device is permanently bound at create, and only
unbound at 'destroy'.

The acpi-einj driver depends on static bind.
