[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]
