doc: drop mention of not implemented SPI transport

The commit 93f2afa45f4c ("initial "transport" framework") adds a
dedicated chapter in the documentation about a possible SPI
transport for flashing.
This transport has never been part of OpenOCD and should not be
listed in the documentation.

Drop the chapter.
