This adds a helper function to exchange a 16 bit number that is to be transferred in big endian order on the wire.
This also fixes a bug, as the free coded byte swap code was incorrect.

Contribution description
This adds
spi_transfer_u16_be()intended to replace the free coded (and buggy) variant in the w5100 driver. This will also be useful for #20301 that needs the same functionality.Testing procedure
The W5100 should work as before on little endian systems, and show now also work on big endian systems. (E.g. running
nativeon a MIPS router with OpenWRT and using the SPI sysfs interface may work.)Issues/PRs references
