roms: Add OpenSBI version 0.4
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.
