[efi] Add the "snpnet" driver
Add a new network driver that consumes the EFI Simple Network Protocol. Also add a bus driver that can find the Simple Network Protocol that iPXE was loaded from; the resulting behavior is similar to the "undionly" driver for BIOS systems. Signed-off-by: Michael Brown <mcb30@ipxe.org>
