feat(notifications): bitmap create at vm load
Hypervisor call FFA_NOTIFICATION_BITMAP_CREATE when loading VMs, to
request SPMC to create bitmap for NWd VMs.
If Hafnium built as SPMC the referred call at load is bypassed.
Adding this to Hypervisor's initialization will allow full notifications
signaling flow with a testing set-up including Hypervisor and SPMC.
