Sebastian Hereu e87cdc40b3 devices: fw_cfg: add fw_cfg device ... Basic implementation of fw_cfg device. The device is recognized by OVMF, and OVMF can read a hard-coded number 0x66 from the device with fw_cfg's read(). Arbitary files can be written to the device via FwcfgDevice::add_file(). The device is activated with the command line param --fw-cfg. Specifying --fw-cfg alone will activate the device and additional arguments may be specified so that a user-specified data blob may be added from the command line. Currently, however, attempting to add a data blob from the command line is a noop.Still need to implement read() and write().
