GUID definition for the Linux Initrd media device path

Linux distro boot generally relies on an initial ramdisk (initrd) which is provided by the loader, and which contains additional kernel modules (for storage and network, for instance), and the initial user space startup code, i.e., the code which brings up the user space side of the entire OS.

In order to provide a standard method to locate this initrd, the GUID defined in this file is used to describe the device path for a LoadFile2 Protocol instance that is responsible for loading the initrd file.

The kernel EFI Stub will locate and use this instance to load the initrd, therefore the firmware/loader should install an instance of this to load the relevant initrd.
