Commit b7bb367afa4b added support for inserting delays in between individual words within a single SPI transaction. This makes it accessible from userspace. WARNING: This delay is silently ignored unless the SPI controller implements extra support for it. This is similar to how the in-kernel users handle the other existing property, spi_transfer->word_delay.
