Vijay Dhanraj d03df0c7e2 HV: Fix MP Init sequence hang by adding a delay
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.
