    Adjust function definition in isa's pnp.c to avoid clang 15 warning
    
    With clang 15, the following -Werror warning is produced:
    
        sys/isa/pnp.c:118:24: error: a function declaration without a prototype is deprecated in all versions of C [-Werror,-Wstrict-prototypes]
        pnp_send_initiation_key()
                               ^
                                void
    
    This is because pnp_send_initiation_key() is declared with a (void)
    argument list, but defined with an empty argument list. Make the
    definition match the declaration.
    
    MFC after:      3 days
    
    (cherry picked from commit 24e8823ef579b99b32c00a7a126a78f91727498a)
