Allow access to QEMU firmware blobs, passed into the guest VM via the fw_cfg device, through SysFS entries. Blob meta-data (e.g. name, size, and fw_cfg key), as well as the raw binary blob data may be accessed. The SysFS access location is /sys/firmware/qemu_fw_cfg/... and was selected based on overall similarity to the type of information exposed under /sys/firmware/dmi/entries/...
