Subject: spi: orion: use new `word_delay` field for SPI transfers

Git-commit: 21e26062052c60d31640e614b792473fca787f9f
Patch-mainline: v5.5-rc1
References: jsc#SLE-15847

The `word_delay` field had it's type changed to `struct spi_delay`.
This allows users to specify nano-second or clock-cycle delays (if needed).

Converting to use `word_delay` is straightforward: it just uses the new
`spi_delay_exec()` routine, that handles the `unit` part.
