    rs6000: Allow MMA built-in initialization regardless of compiler options

    Built-in initialization occurs only once and fairly early, when the
    command line options are in force.  If the -mcpu=<CPU> is pre-power10,
    then we fail to initialize the MMA built-ins, so they are not
    available to call in a #pragma target/attribute target function.
    The fix is to basically always (on server type cpus) initialize the MMA
    built-ins so we can use them in #pragma target/attribute target functions.
