HV: Add one hcall to set the upcall vector passed from sos_kernel

Browse Source 
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.

In order to switch the notification vector from PLATFORM_IPI to
HYPERVISOR_CALLBACK_VECTOR, one API is added so that sos can configure
the up-notifier interrrupt vector.
