[proto] Remove unsupported FSP protocol
The FSP protocol code came from legacy Etherboot and was never updated to work as a gPXE protocol. There has been no demand for this protocol, so this patch removes it. Signed-off-by: Stefan Hajnoczi <stefanha@gmail.com> Signed-off-by: Marty Connor <mdc@etherboot.org>

- * This file provides support for FSP v2 protocol written from scratch *
- * by Radim Kolar, FSP project leader. *
- * *
- * ABOUT FSP *
- * FSP is a lightweight file transfer protocol and is being used for *
- * booting, Internet firmware updates, embedded devices and in *
- * wireless applications. FSP is very easy to implement; contact Radim *
- * Kolar if you need hand optimized assembler FSP stacks for various *
- * microcontrollers, CPUs or consultations. *
- * http://fsp.sourceforge.net/ *
- * *
- * REVISION HISTORY *
- * 1.0 2005-03-17 rkolar Initial coding *
- * 1.1 2005-03-24 rkolar We really need to send CC_BYE to the server *
- * at end of transfer, because next stage boot *
- * loader is unable to contact FSP server *
- * until session timeouts. *
- * 1.2 2005-03-26 rkolar We need to query filesize in advance, *
- * because NBI loader do not reads file until *
- * eof is reached.
- * REMARKS *
- * there is no support for selecting port number of fsp server, maybe *
- * we should parse fsp:// URLs in boot image filename. *
- * this implementation has filename limit 255 chars. *
