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.
