[PATCH] SPI doc clarifications
This clarifies some aspects of the SPI programming interface, based on
feedback from Hans-Peter Nilsson. The in-memory representation of words is
right-aligned, so for example a twelve bit word is stored using sixteen bits
with four undefined bits in the MSB. And controller drivers must reject
protocol tweaking modes they do not support.
