Andrzej Jakowski 6cf9413229 nvme: introduce PMR support from NVMe 1.4 spec 
This patch introduces support for PMR that has been defined as part of NVMe 1.4
spec. User can now specify a pmrdev option that should point to HostMemoryBackend.
pmrdev memory region will subsequently be exposed as PCI BAR 2 in emulated NVMe
device. Guest OS can perform mmio read and writes to the PMR region that will stay
persistent across system reboot.
