  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.

  ssi: Implemented CS behaviour

Added default CS behaviour for SSI slaves. SSI devices can set a property
to enable CS behaviour which will create a GPIO on the device which is the
CS. Tristating of the bus on SSI transfers is implemented.

  ssi: Added create_slave_no_init()

Slave creation function that can be used to create an SSI slave without
qdev_init() being called. This give machine models a chance to set properties.

  qdev: allow multiple qdev_init_gpio_in() calls

Allow multiple qdev_init_gpio_in() calls for the one device. The first call will
define GPIOs 0-N-1, the next GPIOs N- ... . Allows different GPIOs to be handled
with different handlers. Needed when two levels of the QOM class heirachy both
define GPIO functionality, as a single GPIO handler with an index selecter is
not possible.
