drivers: spi: document expectation on spi config parameter
...
Most if not all drivers use an internal function
spi_context_configured() to bypass reconfiguring the SPI peripheral
when nothing has changed. That function determines change based on
comparing the struct spi_config pointer that was last used. This does
not work if a user changes fields within the pointed-to structure.
Document that pointer comparison may be used to detect changes.
