[RFC PATCH 12/15] spi: spi-loopback-test: use new `delay` field

[Alexandru Ardelean]

This change replaces the use of the `delay_usecs` field with the new
`delay` field. The code/test still uses micro-seconds, but they are now
configured and used via the `struct spi_delay` format of the `delay` field.
