As per the BWG a delay should be provided between the INIT IPI and Startup IPI. Without the delay observe hangs on certain platforms during MP Init sequence. So Setting a delay of 10us between assert INIT IPI and Startup IPI. Also, as per SDM section 10.7 the the de-assert INIT IPI is only used for Pentium and P6 processors. This is not applicable for Pentium4 and Xeon processors so removing this sequence.
