In this commit SPI shift engine and sequencer logic is implemented.
Shift engine performs serialization and de-serialization according to the
control by the sequencer and according to the setup defined in the
configuration registers. Sequencer implements the main control logic and
FSM to handle data transmit and data receive control of the shift engine.

SPI controller device model supports a connection to a single SPI responder.
This provide access to SPI seeproms, TPM, flash device and an ADC controller.
All SPI function control is mapped into the SPI register space to enable full
control by firmware. In this commit SPI configuration component is modelled
which contains all SPI configuration and status registers as well as the hold
registers for data to be sent or having been received.
An existing QEMU SSI framework is used and SSI_BUS is created.
