[PATCH v5 27/36] arm/boot: Warn on orphan section placement

[Kees Cook]

We don't want to depend on the linker's orphan section placement
heuristics as these can vary between linkers, and may change between
versions. All sections need to be explicitly handled in the linker script.

With all sections now handled, enable orphan section warning.
