acrn/vhm: change the default notification vector to 0xF3

Browse Source 
Currently the SOS kernel will call hcall_set_callback_vector to config
the expected up-notification vector(0xF3) and then hypervisor uses the
passed vector to raise the interrupt to SOS when needed.
As sos kernel already switches to 0xF3 notification vector, the default 
notification vector can be changed from 0xF7 to 0xF3. In such case it still
can work well even when the SOS kernel doesn't reconfigure the notification
vector.
