HV: Use the variable to fire VHM interrupt

Browse Source 
This is to do the preparation of switch the notifier vector from
PLATFORM_IPI to HYPERVISOR_CALLBACK_VECTOR.

Currently the acrn-hypervisor is using the PLATFORM_IPI vector to notify
the sos_kernel. And then sos_kernel will handle the notification from acrn
hypervisor in PLATFORM_IPI ISR. But as the PLATFORM_IPI ISR can be registered
by the other modules, it will have the conflict when trying to register
acrn intr ISR. So the HYPERVISOR_CALLBACK_VECTOR will be used instead.
