cpu/x86/lapic/lapic_cpu_init.c: Remove double startup IPI for AMD AGESA processors

Many CPU families no longer need the double startup IPI.
    Add CPU_AMD_AGESA as one indicator that it is not needed,
    as all AMD processors using AGESA – currently
    Family 10h to 15h – should not need it.

Successfully tested on ASRock E350M1 with a Family 14h processor.

This is a kludgy approach but it works.
