Kernel: Add some mission sections to the aarch64 linker script

Browse source 
The sections did end up in the ELF file, however they weren't
explicitely mentioned in the linker.ld script. In the future, we can add
the --orphan-handling=error flag to the linker options, which will
enforce that the sections used in the sources files also are mentioned
in the linker script.
