power: vexpress: add suppress_bind_attrs to true

commit 73174acc9c75960af2daa7dcbdb9781fc0d135cb upstream.

Make sure that the POWER_RESET_VEXPRESS driver won't have bind/unbind
attributes available via the sysfs, so lets be explicit here and use
".suppress_bind_attrs = true" to prevent userspace from doing something
silly.
