Aleksandr already gave you a link to the only thing which exists, a
stripped-down, spi-master-only driver without dma support, written for
the LPC variation of the pl022 hardware.  It appears to be a very old
driver with no support for FDT data.  But it's the only thing that
exists right now for freebsd.

It might be worth checking whether netbsd or openbsd has a driver,
those can often be ported to freebsd without much trouble.
