spi: spidev: use new `delay` field for spi transfers
The `delay` field has type `struct spi_delay`. This allows users to specify nano-second or clock-cycle delays (if needed). Converting to use `delay` is straightforward: it's just assigning the value to `delay.value` and hard-coding the `delay.unit` to `SPI_DELAY_UNIT_USECS`. This keeps the uapi for spidev un-changed. Changing it can be part of another changeset and discussion.
