OpenSBI contains platform-specific code, so very much like Linux,
U-Boot or other bootloaders, using the upstream version of OpenSBI
will very often not be sufficient.
This commit therefore adds the possibility of specifying a custom
version of OpenSBI, either custom from upstream, custom tarball, or
custom from Git. Support for other version control systems has not
been implemented for now, but could be added later if needed.

[Thomas:
- Config.in: move the BR2_TARGET_OPENSBI_PLAT dependency to a
"depends on", there's no need to have an if...endif block just for
that.
- Config.in: drop the BR2_TARGET_OPENSBI_LIBRARY_ONLY dependency,
since this option doesn't exist
- opensbi.mk: don't use qstrip on BR2_TARGET_OPENSBI_LINUX_PAYLOAD,
since it's a boolean option
- opensbi.mk: use += when adding linux to DEPENDENCIES
- opensbki.mk: refactor the firmware file installation with a loop]

OpenSBI is a much improved alternative to BBL (riscv-pk). Add OpenSBI
support to buildroot.
