spi: Add FSI-attached SPI controller driver
There exists a set of SPI controllers on some POWER processors that may be accessed through the FSI bus. Add a driver to traverse the FSI CFAM engine that can access and drive the SPI controllers. This driver would typically be used by a baseboard management controller (BMC). The SPI controllers operate by means of programming a sequencing engine which automatically manages the usual SPI protocol buses. The driver programs each transfer into the sequencer as various operations specifying the slave chip and shifting data in and out on the lines.
