    xen/efi: Fix build with clang-5.0
    
    The clang-5.0 build is reliably failing with:
    
      Error: size of boot.o:.text is 0x01
    
    which is because efi_arch_flush_dcache_area() exists as a single ret
    instruction.  Mark it as __init like everything else in the files.
    
    Spotted by Travis.
