    arm64/traps: fix MISRA C 2012 Rule 8.4 violations
    
    Add a function prototype for do_bad_mode() in <asm/arm64/traps.h> and 
include
    header <asm/traps.h> in traps.c, so that the declarations of the functions
    do_bad_mode() and finalize_instr_emulation(), which have external linkage,
    are visible before the function definitions.
