    sim/sh: Remove redundant function declaration
    
    Clang generates a warning if there is a function declaration/definition
    with zero arguments.  Such declarations/definitions without a prototype (an
    argument list) are deprecated forms of indefinite arguments
    ("-Wdeprecated-non-prototype").  On the default configuration, it causes a
    build failure (unless "--disable-werror" is specified).
    
    But there is another issue.  This function declaration in sim/sh/interp.c
    is completely redundant.  This commit just removes that declaration.
