arch/riscv: Allow adding OpenSBI as external blob
The reasoning is that even though vendors currently tend to open source
their OpenSBI implementation, they often do so in their own repository.
So instead of adding all possible source repositories as submodules, we
shall allow specifying a path to an already compiled OpenSBI ELF file.
This is similar of what we currently do on ARM64 with the BL31 binary.
