arch/mips/include/asm/mips-boards/launch.h needs an include guard
to prevent it from being #included more than once.
Prevents these build errors:
In file included from ../arch/mips/mti-malta/malta-amon.c:16:
../arch/mips/include/asm/mips-boards/launch.h:8:8: error: redefinition of 'struct cpulaunch'
8 | struct cpulaunch {
