If CONFIG_ENV_SOURCE_FILE is empty and the default filename is not present, then
the old-style C environment is used instead. See below.
Some boards use a CONFIG option to specify the value of this variable. This is normally handled by efi_get_distro_fdt_name() but in the case of sunxi this does not work, since 'soc' is sunxi, but the files are in the allwinner directory. Provide a work-around for this particular case.
