arm64: vmlinux.lds.S: don't discard .exit.* sections at link-time
.exit.* sections may be subject to patching by the new alternatives framework and so shouldn't be discarded at link-time. Without this patch, such a section will result in the following linker error: `.exit.text' referenced in section `.altinstructions' of drivers/built-in.o: defined in discarded section `.exit.text' of drivers/built-in.o Signed-off-by: Will Deacon <will.deacon@arm.com>
