Add OpenSBI version 0.4 as a git submodule and as a prebult binary.
OpenSBI (https://github.com/riscv/opensbi) aims to provide an open-source
reference implementation of the RISC-V Supervisor Binary Interface (SBI)
specifications for platform-specific firmwares executing in M-mode. For all
supported platforms, OpenSBI provides several runtime firmware examples.
These example firmwares can be used to replace the legacy riscv-pk bootloader
and enable the use of well-known bootloaders such as U-Boot.
OpenSBI is distributed under the terms of the BSD 2-clause license
("Simplified BSD License" or "FreeBSD License", SPDX: BSD-2-Clause). OpenSBI
source code also contains code reused from other projects desribed here:
https://github.com/riscv/opensbi/blob/master/ThirdPartyNotices.md.
In this case all of the code we are using from OpenSBI is BSD 2-clause
as we aren't using the Kendryte code (Apache-2.0) with QEMU and libfdt
is dual licensed as BSD 2-clause (and GPL-2.0+). OpenSBI isn't being
linked with QEMU either it is just being included with QEMU.

1) The GPL says that "if the Program does not specify a version number
of this License, you may choose any version ever published by the Free
Software Foundation". This is not true, QEMU includes parts that are
v2-only.
2) Provide a default for files with no licensing information.
3) It is not just hardware emulation that is under BSD license.
4) Restrict GPLv2-only contributions to user mode emulation (due to
code from Linux) and PCI passthrough (due to code from Neocleus).
5) The rules were initially set by Fabrice but are being amended by
other people (already in commit ee12e1f, LICENSE: There is no libqemu.a
anymore, 2011-11-15). Do not put words in his mouth.
