powerpc/e500: Add missing prototype for 'relocate_init'

Kernel test robot reports:

 arch/powerpc/mm/nohash/e500.c:314:21: warning: no previous prototype for 'relocate_init' [-Wmissing-prototypes]
     314 | notrace void __init relocate_init(u64 dt_ptr, phys_addr_t start)
         |                     ^~~~~~~~~~~~~

Add it in mm/mmu_decl.h, close to associated is_second_reloc
variable declaration.
