Cr50: Simplify the API for the SPS driver
The SPS (SPI Slave) driver handles incoming traffic from the SPI
master. This abstracts the basic hardware functions into a clean
API so that the response to the SPI bytes can be put into
separate files.
BUG=chrome-os-partner:40969
BRANCH=none
TEST=make buildall
If CONFIG_SPI is not defined, incoming SPI traffic is completely ignored.
Even when it's enabled, nothing is reacting to the traffic so
incoming SPI bytes return 0xFF bytes to the master (SPI traffic
is always bidirectional).
