caif-driver: Add CAIF-SPI Protocol driver.
This patch introduces the CAIF SPI Protocol Driver for
CAIF Link Layer.
This driver implements a platform driver to accommodate for a
platform specific SPI device. A general platform driver is not
possible as there are no SPI Slave side Kernel API defined.
A sample CAIF SPI Platform device can be found in
