device-google-x64cros: move gpu fw to initramfs-extra (MR 5730)

oem-* packages put fw into the initramfs, which allows for display/gpu
to work properly early during boot. On x64cros, there's not enough space
in the boot partition to hold gpu firmware so this patch duplicates some
things from oem-* packages in order to put the fw into initramfs-extra
