The Nitro Enclaves (NE) driver communicates with a new PCI device, that is exposed to a virtual machine (VM) and handles commands meant for handling enclaves lifetime e.g. creation, termination, setting memory regions. The communication with the PCI device is handled using a MMIO space and MSI-X interrupts. This device communicates with the hypervisor on the host, where the VM that spawned the enclave itself run, e.g. to launch a VM that is used for the enclave. Define the MMIO space of the PCI device, the commands that are provided by this device. Add an internal data structure used as private data for the PCI device driver and the functions for the PCI device init / uninit and command requests handling.
