[U-Boot] [PATCH] common: spl_fit: Allow firmware image if no loadables

[Abel Vesa]

If CONFIG_SPL_OS_BOOT and FIT_IMAGE_TINY are enabled,
the os will not be set to anything and therefore will
remain as IH_OS_INVALID. What's needed here is to
have IH_OS_U_BOOT as default. And since using the
mkimage oneline command (that is, no its file), the
loadables can't be specified, so we allow firmware
as a fallback.
