OpenSBI 0.8 backport

[Dimitri John Ledkov]

OpenSBI 0.8 backport

[Impact]

 * OpenSBI is used to create RISC-V images for various boards and to boot RISC-V virtual machines.

 * 0.7 & 0.8 add support for more hardware, but are otherwise backwards compatible.

 * qemu/virt file location got moved to generic, add backwards compatible symlink for it, to avoid breaking any stable users.

[Test Case]

 * Boot cpc hirsute cloud image using opensbi fw loader from qemu/virt and generic location

[Where problems could occur]

 * OpenSBI adds more hardware features, which some kernels might not be compatible with. Given how quickly the platform evolves newer OpenSBI is better. But things may fail to boot, or missbehave - i.e. a VM that used to boot and not work, will now boot and not work differently =) for example there are shutdown/poweroff/reboot issues with any sets of opensbi & Ubuntu kernels.

If it does not fix the bug for you, please add a comment stating that, and change the tag to verification-failed-focal. In either case, without details of your testing we will not be able to proceed.

Further information regarding the verification process can be found at https://wiki.ubuntu.com/QATeam/PerformingSRUVerification . Thank you in advance for helping!

Booted.

with

$ dpkg-query -W | grep -e qemu-system-misc -e u-boot -e opensbi
opensbi 0.8-1~ubuntu0.20.04.1
qemu-system-misc 1:4.2-3ubuntu6.10
u-boot-qemu 2020.10+dfsg-1ubuntu0~20.04.1

Thus confirming that both existing, and future proof usecases of opensbi work correctly.
