    xen/arm64: head: Mark the end of subroutines with ENDPROC (take two)
    
    Commit 13c03002c5df ("xen/arm64: head: Mark the end of subroutines
    with ENDPROC") intended to mark all the subroutines with ENDPROC.
    
    Unfortunately, I missed fail(), switch_ttbr() and init_uart(). Add
    ENDPROC for the benefits of static analysis tools and the reader.
