ssi: Support for multiple attached devices

Removed assertion that only one device is attached to the SSI bus.

When multiple devices are attached, all slaves have their transfer function
called for transfers. Each device is responsible for knowing whether or not its
CS is active, and if not returning 0. The returned data is the logical or of
all responses from the (mulitple) devices.
