This patchset adds support for DesignWare DWC_ssi. This soft IP
is an AMBA version 2.0-compliant AHB slave device. Existing driver
already supports the older APB version.

Intel Keem Bay SPI controller is using this IP. This patchset is
tested on Keem Bay evaluation module board.

Changes since v1:
- Rework the third patch based on Rob's feedback.
