hv: Inter-VM communication config for hybrid_rt on whl-ipc-i5

Browse Source 
add an IVSHMEM regoin and the related configuration parameters in
hybrid_rt scenario on whl-ipc-i5. The size of the shared memory is
2M, and it is used for the communication between VM0 and VM2.

v6: rename shm name; remove unnecessary MACROs.

v7: rename MACRO for shm name; add unassigned vbdf for post-launched
    VMs.
