PATCH v5 1/1 NVMe: Initial commit for new storage interface

Initial commit for emulated Non-Volatile-Memory Express (NVMe) pci storage device.

NVMe is an open, industry driven storage specification defining an optimized register and command set designed to deliver the full capabilities of non-volatile memory on PCIe SSDs. Further information may be found on the organizations website at:

http://www.nvmexpress.org/

This commit implements the minimum from the specification to work with existing drivers.
