acrn-config: move the MACRO of IVSHMEM shared region name to ivshmem_cfg.h

Browse Source 
The MACRO of IVSHMEM shared region name is relevant to scenario, move
the MACRO from pci_devices.h which should be consistent for different
scenarios to ivshmem_cfg.h which is the configuration for IVSHMEM and
could vary in sceanrios.
