The current code is apparently not capable, but it shouldn't be too
difficult to re-use the built-in firmware.  i.e. essentially copying
fw_get_builtin_firmware() in drivers/base/firmware_class.c.

Also the bootsplash can appear after mounting the rootfs, too.  Before
that, it's simply a blank screen.  So it's not entirely useless even
without initrd / initramfs.
